ARIN 38 Daily Recap 2

By Jennifer Bly, Public Relations and Social Media Coordinator, ARIN

Today marked the last day of the ARIN 38 Public Policy and Members Meeting in Dallas, Texas.  In the morning we continued the public policy portion of the event and then in the afternoon we concluded with the members meeting.  See yesterday’s blog for a recap of Day 1, and stay tuned to find out what happened today on Day 2.


First we heard a report on the current activities of the Number Resource Organization (NRO), which included confirmation that as of October 1st, the Service Level Agreement between the five RIRs and ICANN for IANA operations is in effect. Then a law enforcement agency (LEA) panel presented on the importance of accurate Whois data for public safety.  Representatives from the FBI, DEA, and Royal Canadian Mounted Police shared their intent to use the public policy process to collaborate with the community to address their concerns about the reliability of data in the RIR’s databases that they rely on as a first step in many criminal investigations. LEAs plan to propose policies in each RIR within the next year aimed at requiring network operators to regularly update their Whois information.

Then the community launched into two policy discussions, including Recommended Draft Policy ARIN-2016-6: Eliminate HD-Ratio from NRPM and Draft Policy ARIN-2016-3: Alternative simplified criteria for justifying small IPv4 transfers.

ARIN 38 Daily Recap

After wrapping up policy talks, we heard about completed and forthcoming organizational software projects and the ARIN Services Working Group, which is tasked with facilitating discussion with the community and developing recommendations.  We also received reports from Engineering, Registration Services, the Advisory Council, Board of Trustees, and we took a look at ARIN finances.  A few observations include that since IPv4 depletion, requests for IPv4 address space has been decreasing while pre-approvals and specified recipient transfers have been increasing. IPv6 request traffic has remained steady, with an increase in help desk inquiries.  For the first time, the percentage of ISP members with both IPv4 and IPv6 holdings surpassed those with IPv4-only.

As always, an open microphone session rounded out the meeting where people brought up their thanks for the fellowship program and issued a reminder to vote.  Also, it was stated that as of yesterday, all of the root name servers have IPv6 addresses in production.

Thanks for your participation in ARIN 38!  Your input in the policy process and ARIN community is very important.  Today’s slides are already posted online divided among Public Policy Meeting Presentations and Members Meeting Presentations. Within the next week we’ll also be adding webcast recordings, full transcripts, and abbreviated notes as well. Be sure to save the date for ARIN 39 in New Orleans, LA from 2-5 April 2017.

ARIN 38 Daily Recap

The ARIN 38 Public Policy and Members Meeting in Dallas, Texas has begun. We’ve already had several interesting policy discussions with more on the way tomorrow. If you missed it, here’s a recap of what happened today and quick look at what you’re tweeting.

A Newcomer Orientation kicked off the program on Wednesday afternoon. First time meeting attendees learned more about what to expect over the next couple of days. Thursday morning the day began with a warm welcome from ARIN’s President and CEO and then a staff Policy Implementation and Experience Report.  Then the Advisory Council Chair presented on-docket proposals, which included the following six policies for today:

In addition to policy discussions, we also had two reports, one an overview of Internet Engineering Task Force (IETF)  activities and another on the Number Resource Organization (NRO) Number Council.  During lunch attendees had the option to discuss ongoing topics of interest ranging from how can we expand ARIN diversity and participation to how inter-RIR transfers are working.  For the first time, we also held a women’s networking lunch for attendees to connect with one another and share common experiences.  In the afternoon, we heard speeches from ARIN election candidates as the polls opened.  If your organization is an ARIN member, and you are the voting contact, be sure to cast your ballot in the NRO NC, Board, and Advisory Council elections.

ARIN 38 AC members ARIN 38 Vint Cerf

After candidate speeches, AC members not running for reelection – Cathy Aronson, Milton Mueller, and Kevin Blumberg were recognized for their many years of service on the Advisory Council.  Board member, Vint Cerf, also not seeking reelection, received a standing ovation for his outstanding contributions to the ARIN community as member and chairman of the ARIN Board.

Throughout the meeting we’ve been tweeting with the hashtag #ARIN38 and hope you will too.  Here’s a sample of what you’ve been saying so far:

The day concluded with an open microphone session for anyone to speak up on any topic.  If you’d like to refer to anything you’ve heard today, today’s slide decks are already available and in the next few days the meeting webcast archives, transcripts, and summary notes will be posted as well. Please plan on returning again tomorrow morning for more great sessions starting at 9 AM CDT whether you’re with us in the Lone Star State in person or you’re in the comfort of your own living room via remote participation online.

Get to Know the ARIN 38 Fellows

By Wendy Leedy, Member Engagement Coordinator, ARIN

ARIN 38 is right around the corner! Are you planning to join us in Dallas? If so, I encourage you to take a moment during the meeting to say hello to our newest fellows. We’ll have 11 fellows in attendance at ARIN 38, and I consider myself very lucky to have gotten the chance to get to know them in the past couple weeks. Now, here’s your chance to get to know them before the meeting!

ARIN 38 Fellows

Perhaps the first (and most obvious!) question I asked each fellow was, “Why did you apply for a fellowship?” I figured this question would give me the best insight as to what matters most to our fellows. Alfredo Calderon-Serrano said he applied at the suggestion of ARIN’s very own Director of Communications and Member Services, Susan Hamlin, and he wanted “to better understand the mission and range of ARIN and how academia can benefit from ARIN services.” (And apparently the word is out, because Shaun Rossi was also encouraged to apply by a peer when discussing IP addressing and ARIN!) Orin Roberts is looking for “more intimate knowledge of how the ARIN community works; from draft policy consultations to technical implementations.” Bradley Fidler and Jason Bothe both agreed that attending an ARIN Meeting would give them the best chance of understanding more about Internet governance and the role of the individual Regional Internet Registries.

Next up, I wondered what are our fellows were most looking forward to at the meeting. Ashell Forde is eager to attend the Women’s Networking Lunch, a new event that will see its first gathering at ARIN 38 (we’re excited about this too, Ashell!). Julie Percival said that getting to meet and work with the people who are most involved with crafting policy would be a highlight for her. And Dustin Phillips summed it up well when he said, “I always look forward to meeting new people with different backgrounds, experience and culture, that ultimately all want to help make the Internet better for everyone.” That’s definitely a noble goal and one that we share here at ARIN.

Perhaps most important of all though, what about the future? How did the fellows foresee themselves contributing to and/or supporting ARIN down the road? There are many ways to get involved, but I was interested in the specifics, and how we might expect to see our fellows engaged in the future.

Gary Campbell, a returning fellow from ARIN 37, intends to improve the awareness level of the work of ARIN and become a member of several related or affiliate groups. Josh Crawford is thinking in terms of business, stating that “being a network administrator for an ISP, I feel that any ARIN Meeting will provide me with ample knowledge and networking opportunities for further personal and business growth.” And lastly, as a former journalist and current communications specialist, Kathleen Monk brings a unique perspective: “I believe I can be an asset to ARIN as I have an ability to clearly communicate technical concepts to the general public and can be a conduit to government, the Canadian media and civil society.” We’re aware of the highly technical nature of our work, so this effort is needed and valued!

With all those great answers, I felt like I had a significantly better grasp on the personality of each of our fellows. But I wanted to know one final thing to tie it all together – in just one word, how did they feel the moment they learned they’d been selected? I think our fellows covered all the positive “E” feelings, because I heard all of the following:

  • Ecstatic (Orin Roberts and Kathleen Monk)
  • Elated (Gary Campbell)
  • Excited (Ashell Forde)
  • Exhilarated (Bradley Fidler)
  • Eager (Jason Bothe)
  • Electric (Josh Crawford)
  • Energized (Julie Percival)

Throw in “stoked” (Dustin Phillips), “delighted” (Shaun Rossi), and “fortunate” (Alfredo Calderon-Serrano), and I think it’s safe to say that being selected is an exceptionally meaningful experience for our fellows. Not only that, it’s been a fantastic experience for me as well to have the chance to get to know our fellows on a more personal level. I’m very excited to meet them in Dallas, and I hope I’ll get to meet you there too!

How to Strategize for Your IPv6 Deployment

By Jennifer Bly, Public Relations and Social Media Coordinator, ARIN

Lately we’ve been sharing with you the results of our recent IPv6 survey. First we took a look at why you decided to deploy IPv6 and who was involved.  Next we examined some of the benefits of IPv6 and overcoming the challenges to IPv6 adoption.  Then we reviewed some of the advice you said you’d give to others in the early stage of their IPv6 journey, and now we’re going to look at even more advice you’d give to your peers just getting ready to deploy IPv6 for themselves.

Start thinking of IPv6 as the main protocol


  • Don’t plan IPv6 the same way you did IPv4. Take a step back and figure out how you would deploy the network if you had absolutely unlimited IPs
  • Think through your addressing scheme carefully. Make sure it is scalable and well understood by administrators
  • Scrub your technical research to eliminate outdated information. Do not assume the most popular search engine hit is the most recent way IPv6 is done
  • Configure your networks in stages out to the customer/business
  • Carefully consider how you will deploy IPv6 in the last mile (firewalls, DNS, DHCP, etc.)
  • Plan your address space properly and logically in order to keep the routing table small
  • Get your own address space and ASN so you can be provider independent

Don’t forget

  • Dual-stack is a mid-point, not an end state: plan all the way through IPv6-only (or at least, IPv6-only with translation at the edges). Put a good project manager on it
  • Budget the funds to upgrade equipment if it doesn’t already support IPv6, don’t buy any new hardware without IPv6 support
  • Stick with it and fix issues as they come up. Don’t just disable IPv6 because that happens to be a quick fix for an issue
  • Make sure all devices are able to do dual-stack. Determine if you plan on using DHCPv6 or self-assigned. Go to as much training as possibly you can!
  • Research your vendors and stress the importance of IPv6 integration into their products and services
  • Find a good ISP with support for IPv6, write it in to vendor contracts

As you get going

  • If it has an IPv4 address, give it an IPv6 address as well. It will save you time and money in the future.
  • The network side of things isn’t that difficult if you have the right infrastructure. Providing key services such as DNS isn’t a problem either. Mail and web services work fine on dual stack systems but if you can separate them it makes finding inter-dependencies easier
  • Watch closely for errors, and make sure you have a rollback plan. Your address plan will need to be rewritten at least once. Accept it, and start with plan A
  • If you’re an ISP, learn how to do dhcpv6 prefix delegation
  • For mobile IPv6 only+CLAT+PLAT, disable dns64
  • Stop trying to NAT IPv6. Static routes are your friend
  • Go for it! It is no­­t that hard. You have to deal with it one way or the other because IPv6 is on your network. It comes enabled by default on most modern OSes. A planned deployment is not only more manageable, but access lists and firewall configurations (to prevent inside spoofing) are taken care of as well

Thanks to all of you who took the time to respond to our IPv6 deployment survey and share your thoughts and experiences with us.  We enjoyed hearing more about where you are on your IPv6 journey, and we’ll be incorporating your feedback into our outreach efforts as we work toward the goal of increasing IPv6 uptake among all organizations that rely on the Internet for their business needs.


Life After IPv4 Depletion

By John Sweeting, Senior Director of Registration Services, ARIN

Believe it or not, it’s been a year since ARIN reached full IPv4 depletion on 24 September 2015. In that time, we’ve seen organizations continue to seek IPv4 addresses via both our IPv4 Waiting List and the IPv4 transfer market. We’ve also seen some exciting strides made toward full IPv6 adoption in the industry and expect to see IPv6 deployments continue to increase within the region. I’d like to share a few observations we’ve made during the past year to ensure networks within the ARIN region can continue to get the resources they need to operate.

Life After IPv4 Depletion

Even though we no longer have IPv4 addresses available in the free pool, many organizations have decided to put their requests on our waiting list of unmet IPv4 requests in the event more IPv4 addresses become available. We’ve checked the couches in ARIN’s offices several times and haven’t found any extra IPv4 addresses under the cushions, but they do occasionally become available either via redistribution from IANA, when addresses are returned to ARIN by the registrant, or when they’re revoked (generally due to an organization’s failure to pay required fees). Unfortunately, the number of requests currently on the waiting list—almost 400!—is far greater than the number of requests we’ve been able to fill from the waiting list (12 via IANA redistribution and one via returned/revoked space). If your organization’s need for IPv4 addresses can’t be delayed indefinitely, you may need to look to the transfer market or to IPv6 rather than pursuing space via the waiting list.

The IPv4 transfer market has been extremely active in the year since IPv4 depletion. Need-based transfer requests have increased almost 400% over that period with a total of almost 100,000 /24s changing hands in those transfers. If your organization is interested in securing IPv4 addresses via the transfer market, ARIN offers a free transfer pre-approval service that allows your organization to have its 24 month need verified by ARIN prior to seeking addresses from a source organization. While not required, pre-approval will help ensure ARIN can process your request as quickly as possible once a transaction is arranged. Organizations with unused IPv4 addresses that are interested in making them available are encouraged to contact ARIN as early in the process as possible to make sure the process goes smoothly. In particular, if the original registrant is no longer in business or has otherwise ceased to exist, a merger and acquisition transfer may be necessary before we’ll be able to help you transfer the addresses to a recipient.

While IPv4 demand continues to be strong, IPv6 is the future of the Internet, and we’ve seen continued steps being taken toward that future over the past year. For the first time, more than half of our subscriber members have registered IPv6 addresses, and we continue to issue IPv6 addresses to 60-100 additional organizations per month. Networks seeking to deploy IPv6 can request IPv4 addresses from ARIN (up to one /24 every six months) from a block that was reserved specifically to assist IPv6 deployment after they register their IPv6 block. One year after IPv4 depletion, more than 99.5% of that reserved space remains available. Organizations adopting IPv6 are encouraged to use this policy after registering an IPv6 block to facilitate their IPv6 deployment.

Looking forward, while we expect IPv4 activity to continue, the reality is that there simply aren’t enough IPv4 addresses to number a world with billions of people each using multiple devices on the Internet. If your organization hasn’t yet deployed IPv6, it’s time to join the movement and start adopting IPv6 today. To make this transition even easier, ARIN’s Board of Trustees recently implemented a new fee schedule that provides for more cost-effective IPv6 registration fees. ARIN’s current IPv6 policies allow almost all organizations to qualify for a block, and once you register a block, you’ll unlock access to the reserved IPv4 block that’s earmarked specifically to assist organizations like yours in their transition to IPv6. For those reasons, if you’ve been postponing your IPv6 deployment, there’s never been a better time than right now to jump in and join the party. Along with everyone at ARIN, I look forward to helping you with that transition in any way I can.


A Quick Guide to ARIN’s Whois

By Leslie Nobile, Senior Director of Global Registry Knowledge, ARIN

ARIN's Whois Service

Most of you have heard of Whois and have some fundamental familiarity with it. But how well do you really know the ins and outs of Whois, and in particular, of ARIN’s Whois service? To help you get a better understanding of how to use ARIN’s Whois service, we’ve developed a Quick Guide to ARIN’s Whois that we think will be your one resource for all things Whois.

First, the basics. The term “Whois” refers to any query and response protocol that is used for searching databases that store registered users or assignees of an Internet resource (e.g. IP addresses or domain names). Specifically, ARIN’s Whois service allows a user to retrieve information about IP number resources, organizations, and Points of Contact (POCs) registered with ARIN. It pulls this information directly from ARIN’s database.

As for how to access Whois, you have a few options. You can use one of the various web interfaces that ARIN (and many others) provide, an Application Program Interface (API), or a command-line interface (CLI) client like the terminal on a Mac or the Windows command prompt. In our quick guide and in this blog, we’ll focus on how to use Whois from a Mac terminal window using different flags to customize your searches.

To submit a Whois query from a terminal, you’ll want to structure your search like this:

whois -h whois.arin.net “flag search-term

The parts of this command are:

  • whois: the command itself
  • -h: specifies that the hostname of the Whois server will follow
  • whois.arin.net: the name of ARIN’s Whois server
  • flag: narrows the search by restricting the results to those that match criteria designated by the flag (this piece varies depending on your search)
  • search-term: the information for which you are searching (this piece varies depending on your search)

Some common types of flags you may use are “n” for the specified network address space, “p” for specified Points of Contact, or “o” for an organization. There are many more flags you can use to narrow your search, so we’ve compiled a complete list of Whois flags you can use. You can also use wildcards in conjunction with any flag.

But once you’ve entered your search, how do you make sense of the results? It’s easy to feel overwhelmed by the lines of text that Whois may display, but once you know what key fields you’re looking for, the results make perfect sense.

The different result fields are grouped into five main categories that are shown below, along with some of the result fields that are returned:

  • Network Information
    • NetRange
    • NetName
    • NetHandle
  • Organization Information
    • OrgName
    • OrgTechName
    • OrgAbuseName
  • ASN Information
    • ASNumber
    • ASHandle
  • Point of Contact (POC) Information
    • Name
    • Handle
    • Company
  • Delegation/Reverse DNS Information
    • Name
    • NameServer

Some other common fields that appear in the results of all kinds of queries include address, “RegDate” (date that the resource was initially registered in the ARIN database), and a last updated date. But keep in mind that this list is not all-inclusive! To see a complete list of all result fields and their respective descriptions, you’ll want to visit the “Interpreting Whois Results” section of the Quick Guide.

Now that you have a better picture of what information Whois contains and how to access it, we hope that you’ll make the most of one of ARIN’s most useful services!

ARIN Policies Start with You!

By Sean Hopkins, Policy Analyst, ARIN

Our prime directive is the administration and management of Internet number resources (IP addresses and Autonomous System Numbers). Between registering, distributing, maintaining, and updating these resources and the records associated with them, there is a lot of work to do, and it’s all guided by our Number Resource Policy Manual, or NRPM. Can you guess where this big book of policies comes from? Believe it or not, it comes directly from people just like you!

You may already know that ARIN policies are community-based, but you may not have known that our community includes anyone and everyone with an interest in Internet number resources, not just those who are within the ARIN region. You might even think you would at least need to be an ARIN Member to help drive ARIN’s Policy Development Process (PDP), but in reality, all you need is an email address to start influencing the future of the Internet.

To submit your very own Internet number resource policy proposal, just fill out our brief template and send it to policy@arin.net. Don’t worry about getting the wording of your proposal exactly right – our Advisory Council (AC) will work with you directly to help transform your idea into a clear change, removal, or addition to policy text, and get it the community attention it needs to move through the PDP.

If you’re more of a visual learner, check out our new video entitled “ARIN’s Policy Development Process” to learn more about each step of the PDP, and become a part of the Internet’s future today!

Word of Advice for Getting Started with IPv6

By Jennifer Bly, Public Relations and Social Media Coordinator, ARIN

This month we’ve been reviewing the results of our recent IPv6 survey. First we took a look at why you decided to deploy IPv6 and who was involved. Next we examined some of the benefits of IPv6 and overcoming the challenges to IPv6 Adoption. Now we are going to look at the advice you said you’d give to others in the early stage of their IPv6 journey.


Here’s a sampling of what you said when asked “If you could give one piece of advice to a company that is just beginning its IPv6 deployment process, what would it be?”:

The big picture

  • Start ASAP, and make it a priority
  • Get full buy in from management
  • Make top-down decisions or policies to include dual-stack as a standard for all new services
  • Start early and define your long-term and short-term strategies and implementation processes before you begin
  • Get high-level support, then focus on security. After approval from CIO and Security to move forward begin training the network team. The training and early implementation need to be close together

How to think about it

  • Take it slow and give your plan due diligence
  • Start thinking of IPv4 as the add-on with IPv6 as the main protocol, not the other way around
  • Make it a matter of pride in the whole company
  • Motivate technical folks to achieve deployment progress through competitions among their peers
  • Be patient and dedicate the proper amount of time to training / research / deploying
  • Think of this as an opportunity to fix all of the mistakes you made in your IPv4 design, so take your time and do it right

Where to start

  • Manage it like any other project and prioritize enabling Internet-facing services ahead of the internal network
  • Get an address assignment and start playing
  • Request enough IPv6 address space to give yourself adequate headroom for growth
  • Prototype in lab environment first, test different IPv6 options to find the right mix
  • Set up test environments to gain experience and then in production, you’ll be surprised at how straightforward it can be
  • Start with customer-facing equipment, email, DNS, website, then your access, and last your business applications
  • Begin somewhere with a small number of hosts/services and block everything at the firewall, opening up only what is needed as it is implemented
  • Start with customer/Internet facing services and then endpoint access, slowly move legacy applications as they become available, use DNS to ‘fix’ services that lack IPv4 support
  • Take your time. Work from the core out and get DNS working rock solid
  • Make sure all routing equipment will support v6, and start deploying inside the network, with translation as a test, then cut over
  • Start at the edge of network and then work inward. End-user devices should be the last step

Knowledge is key

  • Talk to someone who has done it
  • Find trusted advisors
  • Hire a consultant versed in IPv6 to map out and work on the transition
  • Become an expert by getting­­­ training, lots of training for everyone involved

What do you think of this advice? Can you relate? Is it helpful? Do you have more to share? Let us know. Tweet us @TeamARIN on Twitter. In a future post we’re going to look at even more advice you gave in our IPv6 survey and we may feature what you have to say on Twitter as well.

Benefits of Adopting IPv6

By Jennifer Bly, Public Relations and Social Media Coordinator

A couple of weeks ago, we shared some of the results of our recent IPv6 deployment survey with you and promised we’d share a few the benefits our respondents gained from deploying the next generation protocol, as well as how they overcame some of their IPv6 adoption challenges.

In our original post we mentioned that only 20% of respondents indicated “cost” as a barrier to IPv6 adoption within their organizations, many citing technical issues as a larger concern.  So what is the bigger concern? Technical issues. We asked what would have made deploying IPv6 easier for your organization and the most common responses included the need for a better technical understanding inside the organization, training and documentation. Another common answer was the desire to see more vendor support.  A lack of feature parity between IPv4 and IPv6 seems to be a collective pain point in the transition process. More broadly, others indicated they’d like to see an industry-wide consensus to make the move, customer demand, and community support to help drive IPv6 projects inside their own companies. They’d also like to have access to more staffing resources with the appropriate experience.  Lastly, people mentioned that a no hassle IPv6 allocation from ARIN would be nice (which we’re happy to note, is indeed available).

We are deploying IPv6 so we're ready for the future

Benefits of Deploying IPv6

Even though quite a few respondents suggested the tangible benefits of IPv6 deployment are limited at this time, there were several notable perspectives on the benefits of IPv6 deployment, including:

  • More IP space, obviously
  • Future proofing
  • Bragging rights
  • Staying on the forefront of networking and IT trends
  • Leading by innovation and recognition as market leader, both to customers and peers
  • Ahead of the curve instead of behind it, before IPv6 became a critical network dependency
  • Easier to recruit top engineering talent who want to work for a forward-looking company
  • Access to IPv6 only services
  • Simplified access to endpoints, reduced complexity of internal network
  • Better connectivity and easier expansion of public facing services without NAT
  • Meeting US federal OMB requirements
  • Peer routing on partner networks
  • Easier device management and troubleshooting without multiple instances of RFC1918 space to manage
  • ISP customers are able to be assigned an entire subnet, whereas before they could only obtain a single IP
  • Easier to configure internal services on native IPv6 without using up scarce IPv4 resources
  • Less DNS changes
  • Performance and scale
  • Email seems faster
  • Growth of the IoT
  • Meets the demand for mobile devices
  • Makes people feel like they are good netizens

Overcoming the Challenges to IPv6 Adoption

Realistically every business decision and networking problem has its challenges, and IPv6 deployment is no different. Respondents had some great suggestions on how to overcome IPv6 challenges.  In a nutshell, here are few recommendations:­­

  • Just start hacking away at it
  • Slowly enable the core of the network
  • Work on providing IPv6 for externally facing systems
  • Grow on demand with a slow rollout to build confidence
  • Monitor your IPv6 deployment carefully to find any problems early
  • Get training for your IT teams
  • Retire and replace old equipment which does not properly support IPv6: including CPEs, load balancers, device firmware, router CPUs, etc.
  • Request IPv6 support from vendors, opening trouble tickets, and ultimately changing vendors if necessary
  • Make IPv6 support part of your RFP process for new vendors
  • Migrate to IPv6-capable data centers that can accommodate IPv6 upstream providers
  • Have your Internet peers enable IPv6
  • Use third party 6in4 tunnels
  • Treat IPv6 mail with the same rules as IPv4 mail
  • Parallel networks and firewalls, so the IPv6 will be visible to both ISPs and two separate IPv4 ranges will be handling different parts of your traffic
  • Approach the transition as a necessity, not as an annoyance
  • Work with other similar organizations to guide you through the process

Next week we’ll take a look at some of the advice survey respondents said they’d give to others who are planning to deploy IPv6.  Until then, if you’re interested in sharing your advice as well, feel free to tweet your tips and tricks and don’t forget to tag them with the hashtag #get6.


No More Excuses: IPv6 Planning Made Easy

By John Sweeting, Senior Director of Registration Services, ARIN

Planning for IPv6

We know that deploying IPv6 can seem daunting. There’s a lot to think about – is your equipment ready? What about your software? Does your hosting provider support IPv6? Do you have an addressing plan? These are just some of the things you need to ask yourself when getting ready to make the switch to IPv6. And while there are lots of questions to be asked, we would like to focus on the big one that we frequently hear: “How much IPv6 address space do I even need?”

It’s a pretty straightforward question, but we find that a lot of folks aren’t sure how to decide what’s appropriate for their organization. So we’ve developed a brand new webpage dedicated to helping you plan for IPv6, and specifically, helping you determine how much space may be right for you.

It all starts with determining whether you’re an end user or Internet Service Provider (ISP):

  • End users operate networks that do not provide Internet access to external customers.
  • ISPs are either networks that provide traditional Internet access (cable, fiber, wireless, etc.) or they are hosting providers that operate services which provide Internet access (colocation, dedicated servers, virtual private servers, etc.).

Note: End users that are not ISPs but do provide Internet connectivity to users (for example, universities) may apply either as end users or as ISPs.

After that, it’s as easy as 1-2-3!

Step 1: Verify that you qualify for IPv6. End users qualify if they meet any of the criteria below:

  • Have an IPv4 assignment from ARIN or one of its predecessors
  • Intend to immediately be IPv6 multi-homed
  • Have 13 end sites (offices, data centers, etc.) within one year
  • Use 2,000 IPv6 addresses within one year
  • Use 200 /64 subnets within one year

ISPs qualify if they meet any of these criteria:

  • Have an IPv4 allocation from ARIN or one of its predecessors
  • Intend to immediately be IPv6 multi-homed
  • Have a plan to make 50 assignments within five years

IPv6 Block Size TableStep 2: Determine how much space you’ll need. If you’re an end user, block size is determined by the number of end sites in your network, not by the number of IP addresses you anticipate using (see table at right). End sites are physical locations such as offices and data centers. If you’re an ISP, block size is based on the number and size of subnets to be assigned to customers, not on the number of IP addresses required by customers. ISPs will typically assign one subnet (/48 or smaller) to each customer.

If you want to brush up on exactly how many IPv6 addresses a /48, /44, etc. contains, refer to our CIDR chart.

Step 3: You’re almost done! All you need to do after completing steps 1 and 2 is submit your resource request via your ARIN Online account.

That’s it! For more information on the different steps in this process (including more details on determining block size), you’ll want to visit our IPv6 planning page. Our goal is to demonstrate how easy getting IPv6 can be, and we hope we’ve helped you see that making the switch doesn’t have to be confusing. And if you’re ever not sure about something, contact us and we’ll guide you through the process.

Why You Decided to Deploy IPv6

By Jennifer Bly, Public Relations and Social Media Coordinator

We asked you to tell us about your IPv6 deployment journey at your own organization via an open survey.  Out of more than 150 responses, we collected some interesting information that you may enjoy hearing more about.

ahead of the curve ipv6

Some of the services companies provide over IPv6 include (but are not limited to): DNS, DHCP, webhosting, Internet connectivity, network monitoring, email, video streaming, VoIP, ftp, apps, colocation, dedicated server, virtualization, AAAA records, IPTV, WAN uplink, and more.  More than 65% of respondents said they have IPv6-enabled transit and/or peers (77%), network infrastructure (88%), DNS (AAAA or NS records) (67%), and firewalls (72%). However it seems like many organizations still haven’t made their public-facing websites ready for the next generation of the Internet.

steps toward ipv6 survey

Of those who already deployed IPv6, many organizations made the decision to do so because they wanted to futureproof their technology and be experienced with the protocol before customer demand increases.  Many recognized that IPv4 was depleted and that IPv6 is important for business growth.  Some also indicated that deploying IPv6 was a natural progression during planned network improvements that presented little downside.  Several suggested that their company prides itself on being at the forefront of technology, and thus IPv6 was part of their effort to be a market leader and stay ahead of industry trends.  Others indicated that they did not think there is another good long-term solution for dealing with IPv4 scarcity.  International organizations in particular suggested IPv6 is important to connect globally and to be sure customers and clients are able to access them from all over the world.

how long IPv6 survey

Most respondents began work on deploying IPv6 in 2014 (18%) and 2015 (19%) and the process took less than year to complete for more than 45% of respondents. Many internal stakeholders were involved in the decision to deploy IPv6.  A common theme among respondents echoed that executives and management needed to be involved to get the project off the ground.  Specific roles mentioned include: CEO, CIO, CTO, Executive Director, and the like.  From the technical side, implementation involved the IT Department, Network Operations, Systems Administrators, Engineers, Information Services, Technology Directors, and even consultants.  Notably, approval from finance or purchasing was crucial to getting sign off to begin work on IPv6 projects.

Many suggested that deploying IPv6 would have been easier if there had been more of a management push to accomplish it, a hard deadline, and a cross-functional effort across their organization.  Respondents also indicated training would have been helpful, along with examples and best practice documentation from peers.

obstacles IPv6 survey

Interestingly, only 20% of respondents indicated “cost” is a barrier to IPv6 adoption within their organizations, many citing technical issues as a larger concern.  In a following blog post we’ll take a look at how some of our survey respondents overcame a few of their IPv6 adoption challenges. We’ll also share some of the benefits and advice for others that were given. Stay tuned, and in the meanwhile, be sure to follow @TeamARIN on Twitter for some of the feedback from the survey using the hashtag #get6.

Connecting with the Caribbean Internet Community

By Sean Hopkins, Policy Analyst, ARIN

This past week, ARIN joined forces with the Latin America and Caribbean Network Information Centre (LACNIC) for the Caribbean Association of National Telecommunication Organizations’ (CANTO) 32nd Annual Conference & Trade Exhibition in San Juan, Puerto Rico. As usual, the welcoming nature of the Caribbean was in full effect, with little mystery as to who the Regional Internet Registries (RIRs) are or why they were present. We had the opportunity to speak with many stakeholders from both the ARIN and LACNIC regions, as well as answer questions about both IPv4 and IPv6 usage, our IPv4 waiting list, ASN requests, Internet Exchange Point (IXP) allocations, IPv6 implementation strategies, and much more!

CANTO 2016

We were fortunate to have a presence not only on the expo floor, but in the speaking rotation as well. Leslie Nobile, ARIN’s Senior Director of Global Registry Knowledge, joined Kevon Swift, LACNIC’s Head of Strategic Relations and Integration, on the “Aligning the Caribbean ICT Calendar” panel discussion to provide updates on IPv6 adoption and RIR initiatives in the Caribbean and beyond. As we continue to encourage the Caribbean Internet community to bring their unique experience and needs to the Internet number resource policy development process, we look for additional opportunities to educate the Caribbean Internet community about everything from requesting Internet number resources to the latest public policy discussions.

Throughout the week we were able to engage with a wide range of community members, and CANTO provided one of the most open and conducive shows for Caribbean engagement that we have had the pleasure of attending. If you did not get a chance to stop by the ARIN/LACNIC booth and would like to participate in our Internet number resource policy discussions and development, ARIN offers a fellowship program to send up to five people per region to each Public Policy and Members Meeting held in the spring and fall of each year. In addition to fellowships, we also offer full remote participation options in case attending in person is not possible. This October we will be headed to Dallas, Texas, and in April 2017, we will make our way to New Orleans, Louisiana, so we hope to see you at an upcoming meeting! We depend on the participation of all of our members to make sure we’re able to meet the needs of our entire region.

Why Learning IPv6 Puts You a Step Ahead in Your Career

Signal to employers that you’re at the top of your game by learning IPv6 now

Guest blog post by Jonathan S. Weissman

ARIN reached the true technical IPv4 Exhaustion on September 24, 2015. Yet back in 2012, I believe that I created and taught the first ever college course held in the United States that was devoted exclusively to IPv6, a summer course at Finger Lakes Community College. The course had a normal 45 hours aggregate meeting time, but it was devoted to just IPv6 and nothing else. Twenty years before that, in 1992, the IETF asked for white papers after multiple proposals to expand IPv4’s 32 bit address space surfaced. RFCs for IPv6 started appearing in 1996, twenty years ago from this summer, in which my IPv6 course is running in its fifth consecutive iteration at FLCC.

Both my FLCC IPv6 course and my personally written exam for the course are certified by the IPv6 Forum, a world-wide consortium, and an official certifying body for IPv6. Students who get a 70% or better on my exam at the end of the semester, will automatically earn their IPv6 Certified Network Engineer – Silver certification from the IPv6 Forum. Adding this certification to their resume will no doubt make a huge impression on potential employers.

IPv6 has, for the last few years, been appearing on industry level certification exams by CompTIA, Cisco, and others. It’s no longer something being shoved under the rug. Especially now that ARIN is “fresh out” of IPv4 addresses, the knowledge of IPv6 becomes more and more of a requirement with each passing day. You can’t simply wait until your company starts using IPv6 before learning about it. With a solid background in IPv6 before it’s needed, you will be able to easily adapt to and adopt this fascinating new protocol with intelligence and efficiency.

Interestingly enough, I recently looked back at the reports from my first industry certification exams, and to my shock, I saw that my Novell CNE and CNA exams from 2000/2001 actually had IPv6 questions. However, at that point, IPv6 was still in its infancy. No one was using it in earnest as we are just starting to do now.

There happens to be a great twist to this story. IPv4 isn’t going away entirely for a very long time. Experts are predicting decades more of IPv4. On January 1, 1983, ARPANET turned off NCP (Network Control Protocol), and flipped on Vint Cerf’s TCP/IP, featuring IPv4 addressing. There has not been, nor will there ever be, a corresponding “flag day” for IPv6. Back then, if you were “connected,” you were a government agency, academic institution, or research institution. Nowadays, all businesses are connected, and some can’t even afford seconds of downtime. Some companies pay extra to their service providers for the “five nines,” 99.999% guaranteed uptime during a year. Therefore, IPv6 education includes incorporating and interoperating IPv6 with IPv4 with dual-stacking, tunneling, or translation.

For my students with IPv6 education (and certification), it shows at the very least that they are progressive, motivated, and a step ahead of the times. It shows that they are scalable, adaptable, and up on the latest and greatest (although as we mentioned, this “latest and greatest” is nearly twenty-five years old). It shows potential employers that when the need arises to start using IPv6 in an incremental fashion, those who have been already working with IPv6 can be trusted as the pioneers, the architects, the leaders for IPv6 deployment. Learning IPv6 now, when you’re not faced with pressure, deadlines, prioritization demands, and more makes the learning process smoother and cleaner. Being able to learn IPv6 now affords you the opportunity to cover both breadth and depth in ways that simply wouldn’t be possible in a more “on demand” environment.

IPv6 is not just about the exhaustion of IPv4 addresses. The Internet is slowly going to turn from IPv4 to IPv6. It’s happening now. Think about business continuity. At some point, if you don’t make the switch, from a business perspective, it could be devastating. IPv6 is also about doing things that simply weren’t possible with IPv4. For example, “Internet of Things” devices simply do not have enough logic to run a dual stacked IPv4/IPv6 combination. Those sensors being placed all over the planet? They’re running native IPv6! Besides sensory networks, think about the control systems. Think about reporting systems. Think about appliances. Think about home entertainment devices.

One more thing, of course…security! Some networks might have IPv6 enabled and might not even realize it. Malicious IPv6 traffic can enter the network, tunneled through IPv4. Firewalls won’t catch it. Neither will IDS/IPS systems. They don’t even know what they’re looking for, as far as IPv6 goes!

Furthermore, you can’t start thinking about IPv6 security mechanisms and implementations without a truly solid background in the IPv6 protocol and all of its subcomponents like Internet Control Message Protocol for IPv6 (ICMPv6), Neighbor Discovery Protocol (NDP), Dynamic Host Configuration Protocol for IPv6 (DHCPv6), link-local addresses, Internet Protocol Security (IPsec), and much more. As my IPv6 course illustrates, there are so many layers and wrinkles to IPv6. You can’t just read a book over a weekend and be ready to deploy IPv6 or, even worse, IPv6 security on a Monday morning. I tell my students, “seeing is believing,” as we spend lots of time on IPv6 labs, while sniffing in Wireshark.

There’s little to no pressure right now to start learning IPv6. As the days, weeks, and months go by, that will become less and less true. The “Internet of Things” and mobile devices are, of course, the big factors responsible for IPv6’s great need right now. Now is the time to start learning IPv6! There will never be a better time!

My Experience as an ARIN Fellow

ARIN 37 Fellow Alyssa Moore shares about her experience as a newcomer to the ARIN community and the policy development process.

Guest Blog by Alyssa Moore

In April I had the good fortune to:

  • Attend an all-expenses-paid meeting in Jamaica
  • Nerd out with Internet community experts and veterans
  • Engage in the best professional development of my career
  • Form relationships with brilliant mentors

Sounds too good to be true, right? Allow me to introduce you to the ARIN Fellowship Program.

During my time as an ARIN Fellow, I learned that Internet number resource policies in the ARIN region are developed entirely by the community. Every word of the Number Resource Policy Manual (NRPM) undergoes rigorous examination in a transparent, community-driven, bottom-up policy development process. This is significant because in an increasingly networked world, we should all have a stake in Internet governance. Number resource policy is of particular importance in light of the recent depletion of the IPv4 address “free pool” in the ARIN region, the development of an IPv4 transfer market, and the slow pace of a global transition to IPv6.

I also learned that ARIN provides multiple avenues to contribute to the formation of policies and processes that underpin global Internet infrastructure. Anyone with an email address can chime in on global Internet policy-making simply by joining and participating in a mailing list.  Anyone can also attend an ARIN meeting, either in person or virtually. And anyone residing in the ARIN region with an interest in Internet governance is encouraged to apply for the Fellowship Program.

Policy Discussion at ARIN 37

While there is much lively discussion on mailing lists or during meetings, I found that some of the most spirited policy conversations took place over breakfast and at after-hours socials. For example, rules around IPv4 address transfers are currently of particular interest to the ARIN community. Some advocate passionately for the application of strict needs tests in cases where limited IPv4 resources are sold in a private transaction. Others support complete liberalization of the IPv4 transfer market, and the rest fall somewhere in between. If you’re involved in politics in any way, this type of problem may sound familiar.

Regardless of where one’s opinions fall on the policy spectrum, each and every person I encountered took the time to engage in a meaningful discussion with me and explain the issues within their historical context. I was floored by how quickly introductions were made and how welcoming the ARIN community is to newcomers. It’s for these reasons that I strongly encourage anyone with a stake in number resources or the larger Internet governance landscape to get out to an ARIN meeting in person. Fellowship applications are currently being accepted for the 20-21 October 2016 meeting in Dallas, Texas through 31 July 2016.

Voting Contact Clean-Up Campaign Now Underway!

By Wendy Leedy, Member Engagement Coordinator, ARIN

Each fall, ARIN’s Membership elects representatives to the ARIN Board of Trustees and Advisory Council. Two out of three years, they also elect one ARIN representative to the Number Resource Organization Number Council (NRO NC). Every member organization – regardless of its size – is permitted one Voting Contact who casts one vote in ARIN Elections. These elections directly shape the future of ARIN, our community, and the Internet itself!ARIN Elections

This year, all eligible voters must log into ARIN Online to access their organization’s ballot, therefore requiring all registered Voting Contacts to have an ARIN Online account to participate – as previously announced, ARIN is improving the security of its voting system and will no longer email web links for casting ballots. To be eligible to vote, an organization must be a General Member in Good Standing (current on all invoices) and must have designated a Voting Contact linked to an ARIN Online account on record by 6 September.

To assist and ensure all eligible member organizations are prepared to vote during ARIN Elections, our team is currently leading an extensive Voting Contact clean-up campaign. Over the past few weeks and in the coming weeks every member organization should receive an email that either:

  • Confirms an organization’s Voting Contact (if there is no change, no action is required)
  • Requests an organization to designate a Voting Contact now
  • Requests your Voting Contact set up their ARIN Online Account and/or validate their being a voting contact for your organization

As Member Engagement Coordinator, I encourage each of you to please take a few minutes to read the email you received and to take any necessary action asked of you as soon as possible. By doing this, you will ensure that you are eligible to vote in this year’s election. Don’t forget that the deadline to establish voter eligibility for Voting Contacts is Tuesday, 6 September 2016.

Since the outcome of ARIN Elections can have a far-reaching impact, it’s not only a privilege for member organizations to participate, but also an important responsibility. Active and ongoing participation in elections demonstrates an organization’s support of and commitment to electing representatives who will drive transparent policy discussion and change; openly listen to, engage with, and fairly represent the community at-large; and work toward advancing the future of ARIN and the Internet.

Have questions or need help establishing your voting eligibility? Contact us at members@arin.net or call 1.703.227.9840, ext. 834. You may also visit our Voting Contacts page for steps on how to view and update your Voting Contact information or create an ARIN Online account.

At ARIN, we recognize you are busy, so we thank you in advance for your time and ongoing involvement in and support of ARIN. We look forward to virtually seeing you at the polls in October! It’s your voice, your vote – make it count!
