ARIN Reaches Final /8 of IPv4 Address Space

By Leslie Nobile, Director of Registration Services, ARIN

On 23 April 2014, ARIN’s IPv4 address inventory dropped to 1.00 /8 (the equivalent of 16,777,216 addresses) which triggered the final phase of our IPv4 Countdown Plan. Read the official ARIN announcement on this milestone.

What is the answer to IPv4 depletion?

IPv4 depletion should come as no surprise to anyone and clearly underscores the need for IPv6. The sheer size of the IPv6 address pool will more than meet the needs of the growing Internet now, and well into the future.  ARIN has been issuing IPv6 address space since 1999 and has been active in educating the community on the importance of IPv6 adoption for many years. For most ISPs who have IPv4 address space directly from ARIN, there will be no additional initial registration fees to obtain an IPv6 address block from ARIN.  End-users who obtain IPv6 address space from ARIN will pay an initial registration fee, and then a small annual maintenance fee of $100.  Take a look at the ARIN fee schedule to learn more about registration fees.

The bottom line is that ARIN has plenty of IPv6 address space for everyone who needs it and we are happy to help you obtain your own block, so please come see us!


ARIN Your Voice Your Community


Can an organization still get IPv4 address space from ARIN moving forward?

Phase 4 of the IPv4 Countdown Plan lays out the steps for how all IPv4 address space requests will be processed going forward.  Every request will be handled in the order it is received, and reviewed by our team of resource analysts. We have been tweaking our processes and procedures in preparation for this final phase of IPv4 depletion since we implemented Phase 1 of the countdown plan in February 2011, so we are ready for the changes that Phase 4 will bring.  However, we do need to state up front that our response times may be impacted by the more complex review process.

If we no longer have the IPv4 block size that an organization qualifies for in our available inventory, , they will be offered the choice to either accept the largest available block size they can justify under policy, or be added to the Waiting List for Unmet Requests in the hopes that a larger block will become available at some point in the future

ARIN’s Remaining IPv4 inventory is detailed on our Countdown Page, including the number of available blocks according to prefix size, ranging from /24 to /9.

If you have any questions about how to obtain IPv4 address space in Phase 4, or how to request IPv6 address space, please feel free to give our Help Desk a call at +1.703.227.0660 or email us at

    ARIN 33 Members Meeting Daily Recap

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

    Daily Recap ARIN 33

    Today’s Members Meeting brought us lots of reports from the global Internet community.  During our first session of the morning, we heard from IANA on a variety of topics including their recent audit, customer service survey, performance standards, delegated new gTLDs, and community representatives for root DNSSEC key signing ceremonies.  A round of applause was instigated for the good work they do.  Other RIRs from around the world updated us on what is going on their respective regions.  Of particular interest: in the RIPE NCC region IPv4 transfers are increasing at a number of about 50 transactions a month, LACNIC could possibly reach their last IPv4 /9 as early as end of this month, and APNIC has seen an increase in new members largely due to smaller organizations coming in to get /22s.

    Throughout the morning we were also told to expect a report from the ARIN fee structure review panel by the end of May which will be followed by online community discussion and a session at our next meeting in October.  We also received a report from the Registration Services Department, and a lot of interesting information was shared, such as:

    • ARIN has seen an 18% increase in IPv4 requests in the past 12 months & requests are becoming more complex
    • So far 71 transfers have been completed to specified recipients
    • 23 Inter-RIR transfers have been completed from ARIN to APNIC
    • The IPv4 Churn shows 3.68 /8s received back since 2004 and a /8 equivalent returned to IANA in 2012
    • The ARIN IPv4 Countdown Plan Phase 4 will begin when ARIN reaches 1 /8 equivalent left

    Similarly some interesting items from our Engineering Department included many highlights:

    • We had a successful conversion with validation of 100% of all data from Oracle to PostgreSQL
    • 81,984 ARIN Online accounts have been activated since inception through Q1 of 2014
    • ARIN Operational Test & Evaluation is a great place to test code and process
    • We are doing lots of interops including RPKI and RDAP
    • We are creating APIs for core services that allow you to create tools and follow your own timeline

    ARIN33 Meeting

    Lastly we got short and sweet reports on ARIN finances, the Advisory Council, and Board of Trustees. Concluding the meeting was one last chance for people to bring up additional topics during a final open microphone session, and much of the discussion focused on 2 byte versus 4 byte ASNs.

    All of the slides from the Members Meeting are already on our website for you to download.  Stay tuned over the next few weeks for full transcripts, notes, and webcasts from every day of the meeting.  To all of you who attended and participated in ARIN 33, thanks for sharing your time, expertise, and insights with us this week!  Save the date for ARIN 34 in Baltimore, Maryland from 9 – 10 October 2014.

      Daily Recap 2: ARIN 33 Public Policy Meeting

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

      Daily Recap ARIN 33

      Another day here at ARIN 33 in the Windy City of Chicago, and it breezed by rather quickly.  Instead of a long-winded explanation, this short daily recap should help you get up to speed.

      A record number of policies were covered during this Public Policy Meeting.  In total, a whopping 14 policies were on the docket.  Today, the seven draft policies that were added to that count included:

      ARIN-2014-3: Remove 8.2 and 8.3 and 8.4 Minimum IPv4 Block Size Requirements

      ARIN-2014-9: Resolve Conflict Between RSA and 8.2 Utilization Requirements

      ARIN-2014-2: Improving 8.4 Anti-Flip Language

      ARIN-2014-1: Out of Region Use

      ARIN-2014-8: Alignment of 8.3 Needs Requirements to Reality of Business

      ARIN-2014-12: Anti-hijack Policy

      ARIN-2014-11: Improved Registry Accuracy Proposal

      All of these discussions will be posted online in webcast, complete transcript, and abbreviated note form in the upcoming weeks, but in the meantime you can refer to the presentation slides already posted on the ARIN website.

      ARIN 33 Day 2

      Besides policy discussions, we blew through a few other agenda items as well.  An NRO global coordination activities update included details on ICANN discussions, I* collaboration, NETmundial, and /1net.  We heard from the NRO Number Council and ICANN ASO on the status of global policy proposals of which there are none at this moment.  We also viewed many worldwide Internet number resources statistics on ASN, IPv4, and IPv6 allocations and assignments. Rounding out the day, a call for questions on recent Internet governance topics like the NTIA announcement to transition the IANA functions was issued, and an interesting conversation resulted.  We finished with a lively open microphone session that covered a range of topics from encouraging adoption of IPv6 to community participation in ARIN processes.

      Again, we enjoyed seeing your tweets about the meeting using the #ARIN33 hashtag. Keep them coming. A few of our favorites from today:

      Don’t forget you can participate in the final day of ARIN 33 without even being physically present in Chicago with us, just take advantage of one of our many remote participation options. See you tomorrow morning at 9 AM CDT for the Members Meeting portion of ARIN 33 (you don’t even have to be a member)!

        ARIN 33 Public Policy Meeting Daily Recap: Day 1

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

        Daily Recap ARIN 33 Day 1 of ARIN 33 blew by in the heart of the Windy City, Chicago.  In case this first day swept by you, here’s a recap of what happened today.

        First and foremost, we tackled several draft policies that sparked interesting debate among ARIN 33 attendees onsite and online.  The seven we discussed today included:

        ARIN-2013-7: NRPM 4 (IPv4) Policy Cleanup

        ARIN-2014-4: Remove 4.2.5 Web Hosting Policy

        ARIN-2014-7: Section 4.4 Micro Allocation Conservation Update

        ARIN-2014-10: Remove Sections 4.6 and 4.7

        ARIN-2013-8: Subsequent Allocations for New Multiple Discrete Networks

        ARIN-2014-6: Remove 7.1 [Maintaining IN-ADDRs]

        ARIN-2014-5: Remove 7.2 Lame Delegations

        ARIN 33 overview

        At the start of the day we got an update from the Advisory Council Chair about on-docket proposals.  Then we took a look at what is going on with policies in other regions around the world including proposals related to both IPv4 and IPv6.  We heard Registration Services’ policy experience examining whether new/first time ISP requestors will be able to qualify for IPv4 space under existing ARIN policies after free pool depletion.

        An IPv6 IAB/IETF Activities Report took a look at what is going on at Internet Engineering Task Force (IETF) meetings.   And an API Software and Development Toolkit session explained how getting an API is easy and ARIN Community Projects. Results from ARIN’s recent customer survey were presented and the community was informed they will be available on the website in the coming weeks.

        We were reminded of how the ARIN Consultation and Suggestion Process works and how to participate, and lastly we heard about the software development projects that have been completed since the last ARIN meeting (like a migration from Oracle to PostgreSQL, a feedback button on the ARIN website, and several others).

        We caught a few you using the #ARIN33 hashtag on Twitter, and encourage you to keep on sharing.  Here are few of our favorite tweets so far:

        If you want to refer to anything you saw or heard at the meeting so far, today’s slides are already up on our website, and webcast archives will be added at a later date.

        Remember, you don’t have to be with us here in Chicago to participate in the rest of the meeting.  We still have two more days of agenda items, and you can watch the webcasts, follow the live transcript, vote in polls, and submit questions and comments via a Jabber chat room.  Please register to take full advantage of our remote participation options. Tomorrow we’re kicking of the meeting at 9:00 AM CDT.  Plus check back here at the end of the day for another Daily Recap.

          2014 WTDC – Looking Forward

          By Cathy Handley, Executive Director Government Affairs, ARIN

          WTDC 14The 2014 World Telecommunication Development Conference (WTDC), centered on the theme of Broadband for Sustainable Development, came to a successful conclusion on 10 April in Dubai, UAE.

          The general tenor of the conference was one of collaboration and open dialogue amongst attendees. The Regional Internet Registries (RIRs) were fully represented and involved. Speaking for ARIN, we were pleased with the amount of interaction with Member States who sought us out during the meeting and at coffee breaks to ask questions and share information. This was clear evidence of the positive progress interaction and acceptance between the public and private sectors has made since the last WTDC in 2010.

          One Resolution of particular interest to our community is Resolution 63, “IP address allocation and facilitating the transition to IPv6 in the developing countries.” This outlines the need for continued education, training and IPv6 capacity building. It invites Member States to engage with relevant parties such as the RIRs for technical guidance and information based on shared experiences throughout our communities.

          While not all of the Resolutions discussed were specific to IP addressing, many covered topics that are just beginning to unfold and will have impacts on the Internet. Issues covered at this WTDC ranged from the introduction of Over The Top (OTT) mobile services to E-Health. The growing reliance on IP addressing for all of these services makes them relevant to ARIN and the RIR communities. In these early stages it is important to build a knowledge base for Member States discussing these Resolutions to ensure that future policy decisions are based on an understanding of the technical operations of the Internet, thus helping to ensure the continued stable growth of the Internet.

          ARIN, as well as the other RIRs, will continue to work with the International Telecommunication Union (ITU) Development Sector and our respective communities toward achieving the end goal of unfettered Internet access throughout the globe.

            By ARIN 33 Fellows: Kevin Powell, Brett Henrich, and Jose Alvarado

            In only days ARIN 33 will be upon us.  Get to know the three fellows who you’ll find actively involved at this meeting with this quick Q&A.

            Kevin PowellKevin Powell

            Lecturer/Head of Department, General Studies and Communication at University College of Caribbean, from Jamaica

            What are you looking forward to in Chicago?

            I do a Google search on Chicago every day just to acclimate myself to this renowned city. I am really looking forward to participate in the ARIN 33 meeting, to learn more about ARIN and its policies, and to really just make my contributions to the discussion surrounding the use of the Internet and specifically issues related to IT governance. In addition, I am really looking forward to networking with other ARIN members and making life long connections.

            What do you intend to accomplish by attending an ARIN Meeting?

            One of the major objectives I intend to accomplish by attending the ARIN conference is to be equipped with knowledge. I desire to be empowered with additional information regarding policies on Internet governance and other matters relating to the distribution of Internet addresses.

            How do you think your ARIN Meeting experience will benefit you or your organization when you return home?

            In line with ARIN’s goals of information publication and dissemination along with education, I intend to participate in and conduct seminars and a conference at the University College of the Caribbean just to sensitize students and other faculty members about any insights gained while at the ARIN Meeting. I intend to write a paper or article to be included in the University’s Journal on The Role of Internet Governance in Education and Training. My particular area of focus will be on the issues of accessibility and policies that can be implemented to assist all the stakeholders in the education sector to maximize their use of the Internet in education.    I intend to also share the knowledge gained at the ARIN conference with other members of the local ISOC chapter in Jamaica of which I am a member.

            Brett HenrichBrett Henrich

            IT Operations Manager at Infracore LLC, from California, USA

            What are you looking forward to in Chicago?

            I’m looking forward to meeting the folks who are working on the front lines of Internet governance in North America at this important time in the Internet’s history, with the US Government’s announcement of the globalization of IANA functions and the exhaustion of ARIN’s IPv4 reserves being key topics of interest to me.

            What do you intend to accomplish by attending an ARIN Meeting?

            I would like get a chance to meet the folks at the heart of the debate over ARIN’s role in the future of the Internet and to lend my voice.    I am also interested in learning more about ARIN’s IPv6 advocacy programs and meeting the people behind those too.

            How do you think your ARIN Meeting experience will benefit you or your organization when you return home?

            I attended an ARIN on the Road event that helped provide meaningful information about the IPv6 transition, and that has enabled me to make stronger cases for IPv6 deployment among the team I work for, who are responsible for managing various enterprise environments.    I also think that it will improve my skills as a network engineer and would love the opportunity to network with similar people in this space.

            Jose AlvaradoJose Alvarado

            Sr Technical Specialist at Allstream Corp., from Ontario, Canada

            What are you looking forward to in Chicago?

            I’m thrilled to be at ARIN’s conference for the first time.  I’m looking forward to learning how ARIN manages and directs its members to make efficient use of IP address, and participate in the thought process for formulating plans to make sure existing IPv4 addresses are used efficiently, and how other members are embracing IPv6. I’m looking forward to contribute on decision-making processes and be part of constructive discussions.

            What interests you about ARIN? 

            The issues surrounding IP address allocations, and policy

            How do you think your ARIN Meeting experience will benefit you or your organization when you return home?

            MTS Allstream is a medium size ISP. That puts us both in the shadow of large ISPs and also able to help smaller providers. This unique position allows us to see policy effects from all perspectives as we are both requesting resources from ARIN as well as processing requests from our customers. We are well advanced in IPV6 deployment and have about 50 IPv6 customers and dozens of IPv6 peers. We can share our experience with it.


            If you’ll be at ARIN 33, be sure to find Kevin, Brett, and Jose to introduce yourself and give them a big welcome to their first ARIN meeting!

              Interop Las Vegas: Doubling Down on IPv6

              By Sean Hopkins, Communications and Technical Writer, ARIN

              Last week, we carved out a corner of the Interop Las Vegas expo floor for any attendees with questions about IPv4, IPv6, ARIN technical services, and so forth. To our delight, we were flooded from start to finish with all manner of organizations from across the region, and questions on nearly every topic! The biggest topic, of course, is IPv6 adoption. More organizations asked us about how to get IPv6 deployed than ever before, and with good reason.

              v6 is in the cards

              Europe and the Asia-Pacific region are dipping well into their final /8, and ARIN is down to just over 1.2 /8 equivalents, putting us on the cusp of the final phase of depletion. Business reasons are already piling up for IPv6 adoption, and we hope that Phase 4 offers a needed nudge for those on the fence about implementing dual-stacked networks now vs. later.

              IPv4 availability has been a global talking point for years, but it’s not just a technical concern. More and more executives and small business owners are coming to us to help put IPv6 on their roadmap. We are thrilled to see that the importance of IPv6 is on the minds of more decision makers and executives than ever before. More CEOs and COOs stopped by our booth than in years past, and each left us with a clear mission to bring their business into the future. Forward-thinking businesses blaze ahead of those pinned down by outdated technology, and if your business still leaves their website and mail servers on IPv4-only networks, you’re part of the old Internet, not the whole Internet.

              If you are interested in obtaining your first IPv6 block, visit ARIN’s resource request section and see just how easy it can be to get your initial allocation or assignment. Once you are ready to get your feet wet, check out our IPv6 Wiki for helpful advice, informative presentations, and real-world IPv6 adoption stories. If you have any questions, feel free to email us at

              A big thank you goes out to all those who came to us with great feedback and questions, and we will see you at Interop New York this October!

                Building a High-Availability PostgreSQL Cluster at ARIN

                By Devon Mizelle, Systems Administrator, ARIN

                Devon MizelleARIN is a small organization with a big job. ARIN keeps track of IP addresses and Autonomous system numbers for both North America and parts of the Caribbean.  This information is kept in a high-availability database that is core to ARIN’s services. This  database is known as Jon Postel’s notebook, in tribute to Dr. Jon Postel who was one of the early luminaries of the Internet and who had the first job to keep track of names and numbers. Until the end of last year, this database resided in an Oracle cluster located in our base headquarters in Chantilly, VA. Over the past couple of years, ARIN has been looking to replace Oracle with the advent of robust Open Source database solution.

                An organizational decision was made to migrate away from Oracle to PostgreSQL as it provided a feature set that we could use. One of the tougher requirements was replicating Oracle’s RAC system to provide us with high-availability for our backend. Through a long and intense period of research, implementation, and testing, we completed the migration to pgSQL late last year. So far, the new system has provided us great results.

                This system is built upon a sturdy foundation made up of the new pgSQL replication functionality in the 9.0 release, the Corosync Cluster Engine, and the Pacemaker cluster resource management system. Using the Pacemaker system, we can monitor the health of each member of the database cluster and gracefully disable a misbehaving node in order to preserve the integrity of our services to the community. The Corosync engine provides the ‘back bone’ that the Pacemaker service uses to talk to each box and describe their health to one another. Essentially, we have been able to closely replicate the RAC system features that we used with Oracle using only open source software!

                As a result of working with the Postgres community, we have been invited to speak at PGConf NYC 2014 about our new PostgresSQL cluster and how we’ve built it! We’re extremely excited about this opportunity and would like to extend an invitation to the rest of our community. If you are attending the conference, or are just in the area, please come out and say hello! You can find more information about the talk and the time it will be at on PGConf NYC’s site.

                  Globalization of the IANA Functions Contract Explained

                  By Cathy Handley, Exec. Director Gov’t Affairs & Public Policy, ARIN

                  You have probably heard some buzz lately about a recent announcement from the U.S. government about plans to transition oversight of the IANA functions contract to the global multistakeholder community.  Headlines in the news have ranged from U.S. to relinquish remaining control over the Internet to The Internet Is About to Take Its Next Giant Evolutionary Leap.  Let’s take a look at what is really happening.

                  Internet Governance Blue Globe

                  The IANA Functions

                  First, taking a giant step backward, it’s important to know – what exactly are the IANA functions?  They are part of Internet infrastructure and include responsibility for allocating and maintaining the unique codes and numbering systems used in Internet technical standards. The specific IANA functions include:

                  • Coordination of the assignment of technical Internet protocol parameters through the Internet Engineering Task Force (IETF)
                  • Administration of and coordination of Internet domain name system (DNS) root zone management
                  • Allocation of Internet number resources to the Regional Internet Registries (RIRs)
                  • Management of the .ARPA and .INT top-level domains (TLDs)

                  The IANA Functions Contract

                  Historically the Internet Corporation for Assigned Names and Numbers (ICANN) has performed the IANA functions, on behalf of the United States Government, through a contract with National Telecommunications and Information Administration (NTIA).  The first contract was awarded in 2000 and then again several more times up until the most recent contract in mid-2012. A few days ago the US government announced that it will begin the long-intended transition of these key Internet technical functions to the global multistakeholder community. As part of this process, ICANN will be responsible for spearheading the development a proposal by the global multistakeholder community for the transition of the current role played by NTIA in the coordination of the Internet’s domain name system (DNS).

                  ICANN Public Consultation Process

                  ICANN will work the Internet Engineering Task Force (IETF), the Internet Architecture Board (IAB), the Internet Society (ISOC), the Regional Internet Registries (RIRs), top-level domain name operators, VeriSign, and other global stakeholders to develop a process to transition the NTIA out of the IANA functions and related root zone management.   ICANN has developed a document detailing the Public Consultation Process that will launch at their upcoming meeting Singapore later this month. Input from these initial community discussions will be compiled for public comment and community feedback to inform the process going forward.

                  Key in the US government announcement was the indication that no proposal that replaces the NTIA role with another government-led or an inter-governmental organization solution will be accepted.  No single country or international organization will be given charge over the IANA functions contract. Instead, the new plan must follow the multistakeholder model, protect the integrity of the Internet DNS, maintain Internet openness, and fulfill needs and expectations of those who rely on the IANA functions.

                  Why Globalize?

                  Globalization of IANA functions contract is critical in developing a true multistakeholder model of Internet governance.  Because the functions include the technical coordination of the global IP address pool and AS number space and Internet number resource allocation to the RIRs this is a subject near and dear to our heart.  We strongly believe that it is essential that the IANA functions are managed in a open, transparent, and globally-accountable manner. Along with leaders of other Internet technical organizations responsible for coordination of the Internet infrastructure, we welcome suggested changes related to the IANA functions contract are pleased to see the globalization of this role.

                  Opinion Statements

                  The Internet Technical leaders aren’t the only ones who issued a statement or provided some input on the US Government announcement on Friday.  Many others have as well.  Here are a few we found from organizations and individuals around the web (let us know in the comments of ones we may have missed):

                  Here’s where it all began:

                    A Process of Refining Policies

                    By John Sweeting, Chair, ARIN Advisory Council

                    ARIN hosted a Public Policy Consultation (PPC) at NANOG 60 in Atlanta, Georgia on February 11. The report for this meeting, which includes presentations, summary notes, webcast archives and transcripts of the entire meeting, is available on the ARIN website.  It includes the presentation and discussion of one recommended draft policy, eight draft policies, and three proposals.

                    The Atlanta PPC was a good example of the how the ARIN policy process works; it is a process of refinement.  Proposals and draft policies go through multiple reviews and revisions before being accepted as Policy and added to the Number Resource Policy Manual (NRPM) or abandoned along the way. The PPC is one tool, along with the Public Policy Mailing List (PPML) and ARIN Public Policy Meetings (PPM), that allows the AC to interact with the community. This particular PPC demonstrated areas where current draft policies required additional review and editing.

                    ARIN Public Policy Consultation PPC

                    Highlights from the Discussion

                    We had some active discussions regarding a few of the policies. I’d like to highlight a some of those discussions so you can get a sense for how the process works.

                    Recommended Draft Policy ARIN-2013-8: Subsequent Allocations for New Multiple Discrete Networks would add definitive criteria to indicate what the requirements are for getting additional space under the multiple discrete networks policy.

                    One community member pointed out that requiring someone to have connectivity prior to getting address space was not conducive to good business practices. A question raised was – if someone needs to get connectivity before they get address space, what happens if they can’t get space after they get connectivity?  The discussion centered on finding language that would work to ensure the business that required address space was not left in a position of paying for services that they could not get addresses for. Follow on discussion has been taking place on the PPML.

                    Draft Policy ARIN-2014-1: Out of Region Use would clearly define and permit out of region use of address space issued by ARIN. It would require that such out of region use be verified the same way that in-region use is verified and would specifically authorize ARIN to contract with out of region providers if necessary to verify that use.

                    It was pointed out this is not intended to change criteria for requesting space, nor does it impact new requests, only how existing space usage is measured.  Others noted if this policy passes, it would speed up depletion of IPv4 at ARIN, and increase the need for inter‑RIR coordination effort.  Concern was also expressed that this could open up the door to position ARIN as a global RIR although that is definitely not the intent.

                    Draft Policy ARIN-2014-7: Section 4.4 Micro Allocation Conservation Update would raise the required number of operators that must get together to justify an allocation from ARIN for an IXP from two to three.

                    During the discussion it was brought up there are not a lot of IXPs in the ARIN regions, so this policy is to encourage conservation and help develop more successful IXPs in the region.  There was also language regarding how to apply fees. Some voiced dissent that this oversteps the scope of the NRPM, and that the Board should only be defining the status of organizations with regard to establishing their billing category (ISP, End-user, etc.)

                    To get a sense for all the conversations that occurred during the policy discussions, check out the  full report for the PPC at NANOG 60. The Atlanta PPC was a great example of how these consultations help gather feedback from the community to hone policy language and positions.  This will help us to use our time more efficiently at ARIN’s next public policy meeting in Chicago this spring as well as help the ARIN Advisory Council present good policy to the community.

                    What’s Next?

                    Whether or not you had the chance to join us remotely or in person for this most recent PPC, I think you will find it worth your time to participate in ARIN 33,  13 16 April in Chicago, Illinois where we will revisit many of these proposals and possibly consider a few new ones as well. In the meantime please share your thoughts and interests in any of these policies with the community on PPML.

                      Still Testing in Production? Now You Can Test Your Code in ARIN’s OT&E

                      By Steve Scally, Systems Administrator, ARIN

                      ARIN has developed some very helpful tools to help users learn about, request, and manage IP addresses and Autonomous System Numbers (ASNs) over the years. Our customers rely on things like ARIN Online and the Whois directory service to manage and monitor the resources their organizations hold. If your job entails keeping Internet number resource records up-to-date, you have most likely used these tools as well, perhaps even multiple times a day.

                      Our more frequent users have even developed their own tools to automate common interaction processes such as Shared Whois Project (SWIP) reassignment reporting. These tools allow for much-needed automation, but they can be difficult to test without a playground of non-production data to interact with. Enter ARIN’s Operational Test and Evaluation environment, or OT&E.

                      First released back in 2011, OT&E has evolved into a full-featured counterpart to ARIN’s production services, filled with mirrored data that gets refreshed from production on the first Monday of each month. If you have been looking for a way to familiarize yourself, your staff, or your software with ARIN’s RESTful and RPKI systems, OT&E is the place for you.

                      ARIN Operational Test and Evaluation Environment

                      Ready to join and get started? Just log into your ARIN Online account and use Ask ARIN to request access! Once we vet your request we’ll hook you up with an account and send you additional OT&E access details.

                        Follow the Policy Path from Proposal to Adoption

                        By Einar Bohlin, Senior Policy Analyst, ARIN

                        Today we are holding our Public Policy Consultation (PPC) at NANOG 60. Members of the ARIN Advisory Council (AC) will be presenting eight draft policies, one recommended draft policy, and three policy proposals. Let’s look at what those terms mean.

                        ARIN Policy Flow Chart

                        First of all, Policy Proposal. A policy proposal is simply a problem statement and an idea for a policy change (eg., ARIN-prop-197 Remove 7.2 Lame Delegations). The AC assigns shepherds to work with the proposal author to ensure that the proposal is clear and in scope.

                        If a policy proposal is confirmed to be clear and in scope by the AC, it’s accepted as a Draft Policy (eg., Draft Policy ARIN-2014-4: Remove 4.2.5 Web Hosting Policy). Draft policies are posted to the Public Policy Mailing list for community discussion. The AC wants to know, is this good idea? Is it clear, technically sound and useful? If the feedback indicates that it is a good policy change, then the AC will work on the text until it is fully developed. It’s at this stage that bad ideas are abandoned. The AC will request an ARIN staff and legal assessment. When the AC believes that the text is fair, technically sound, and has the support of the community (what we call “the principles”) then the AC will recommend it for adoption.

                        After being recommended for adoption, we have a Recommended Draft Policy (eg., Recommended Draft Policy ARIN-2013-8: Subsequent Allocations for New Multiple Discrete Networks). Recommended drafts are posted to the Public Policy Mailing List with a statement from the AC that shows conformance with the principles (fair, technically sound and supported by the community), along with the staff and legal assessments. Recommended drafts must be presented to the community at a Public Policy Consultation before they can go to last call. After presentation and last call, if the AC still supports the Recommended Draft Policy, then the AC will send it to the ARIN Board of Trustees.

                        The Board of Trustees will evaluate to ensure that the Policy Development Process was followed, and a final check to make sure the policy is in compliance with ARIN’s mission.

                        Shortly after adoption by the Board of Trustees, ARIN staff implements the new policy and incorporates it into a new version of the Number Resource Policy Manual (NRPM).

                        More information is available on the policy development page. If you want to get involved in taking ideas from proposal to adopted policy, there are lots of ways for you to join in – on our PPML mailing list, at our PPC today, or at ARIN 33 in the spring.  Get involved and let’s talk policy!

                          Setting a Customer Focused Approach

                          By Richard Jimmerson, Chief Information Officer, ARIN

                          ARIN isn’t an organization I can stay away from for long.  I served a number of roles at ARIN over the course of 13 years, before moving to the Internet Society to implement new programs focused on deploying key Internet technologies.  I was excited to have the opportunity to return to ARIN and lead efforts to hone our focus on the customer and improve the way we serve our community. My main goal is to find out how ARIN’s services and systems can better meet your needs. The first step to meet this goal is to find out exactly what your needs are. Where would you like to see us improve?

                          Tell Us How We Can Help You

                          For the next two weeks, we will be conducting a customer satisfaction survey to determine the current level of customer satisfaction with ARIN services and inform a path forward to make future improvements. Working together with a marketing research firm, Rockbridge Associates, we have developed a survey that will help us assess our performance in all areas of the organization, including Engineering, Registration and Financial Services, Policy Development, and Communications. The survey is open today through Friday, 21 February, so participate now. It should only take around 15 minutes to complete.

                          Your feedback is important to us, and we value your time to help ARIN improve services to you.

                          Win A Prize

                          We will be randomly selecting winners to receive a Nexus 7 tablet during the survey period. If you would like to participate, please provide your name and an email address on the final page of the survey. This information will only be used for the purposes of randomly selecting and contacting survey prize winners. The names of winners will be announced.

                          Take the Survey 
                          ARIN Customer Satisfaction Survey

                          We are looking forward to your feedback in the survey and will work hard to respond to your needs.  I look forward to being your advocate to make interactions with ARIN as productive and efficient as possible.

                            How to Request an ASN from ARIN

                            By The Registration Services Department, ARIN

                            Autonomous System Number ASNThe ARIN Registration Services Department assists many organizations in obtaining Autonomous System Numbers (ASNs).  Last week you may have heard from the NRO that the global pool of available 2-byte ASNs is nearing depletion.  But let’s take a step back.  What is an ASN? Who needs one? Why? And how can you get one if you need one?

                            ASN: The Basics

                            ASN stands for Autonomous System Number.  It is a number that is used to define a group of routing prefixes that maintains a unique routing policy that differs from the routing policies of network border peers. ISPs use ASNs to control routing within their networks and to exchange routing information with other ISPs.  AS numbers (along with BGP) help routers and networks to identify where information comes from and where it should go outside a particular ISP’s network.  A public ASN is needed for an autonomous system to exchange routing information with two or more autonomous systems on the public Internet.

                            2-byte to 4-byte ASNs

                            There are two types of ASNs, 2-byte and 4-byte.  Similar to the case with IPv4 and IPv6 addresses, 4-byte ASNs were developed to meet the growing needs of a rapidly expanding Internet.   There are only 65,536 2-byte ASNs, and the 4-byte range provides an additional 4,294,967,296 AS numbers. Today only 496 2-byte ASNs remain globally. You can still request a 2-byte ASN for as long as we have them to distribute, but soon 4-byte ASNs will become the only option. You will find that the process to request 2-byte ASNs and 4-byte ASNs is the same, so follow along as we tell you how.

                            How to Get an ASN from ARIN

                            The Registration Services Department analyzes and processes many ASN requests each day.  We are happy to report that we are now seeing an uptake in 4-byte ASNs being implemented by our community.  In the past, we saw many people requesting 4-byte ASNs, only to exchange them for 2-byte ASNs the next week because their upstream provider told them they could not support 4-byte ASNs.  This situation seems to be rectifying itself and we are now regularly issuing many more 4-byte ASNs than 2-byte ASNs.

                            To qualify for an ASN from ARIN, you must have either a unique routing policy or a multihomed site.

                            If you are qualifying under the multihomed policy you will need to provide the exterior gateway protocol to be used, the IP addresses currently in use on your network, the AS number and name of each of your upstream providers and/or peers along with contractual verification of service with at least two of them.

                            If you are qualifying under the unique routing policy, you must demonstrate the AS’s routing policy will differ from the routing policies of its border peers.

                            No matter which policy you qualify under, if this is not your first time requesting an ASN, you will also need to show us how the network you are requesting an ASN for is autonomous from all existing ASes in your network as well.

                            If you meet the requirements, the next step is to apply for your number. That process works just like any other Internet number resource request.

                            • Submit your request through ARIN Online
                            • We will verify your request and issue a ticket for tracking purposes
                            • Then we will review your request. We may have questions, and that communication will happen in your ticket.
                            • If your request is approved, you will receive an invoice and a Registration Services Agreement.
                            • Once we receive payment and a signed agreement, we will be able to complete the ASN assignment.

                            It’s that simple! If you have any questions along the way applying for your ASN, let us know.  You can email us at or call us at +1.703.227.0660. The RSD staff would be happy to help you.

                              IPv6 Advice for Service Providers and Home Users

                              Preparing for IPv6 is easier than you’d think. Chris Phillips, Managing Partner of Aptient Consulting Group gives some useful advice for service providers and home users who are ready to make the effort toward IPv6.

                              Guest Blog Post by Chris Phillips

                              Oliver Wendell Holmes once said, “The mode by which the inevitable comes to pass is effort.” With ARIN’s available IPv4 addresses dipping below 1.5 /8s, an IPv6 Internet is inevitable. But the effort bit is underwhelming, at best.

                              At the current rate the old addresses are being acquired, we may see complete IPv4 depletion by the end of 2014. Yet just a slim 12 percent of the Alexa top 1000 most-visited websites on the Internet are reachable through IPv6. An even more minuscule 2.75 percent of Internet users reach Google via IPv6. And according to the Amsterdam Internet Exchange – the world’s largest single Internet exchange point by member ports – a paltry 0.6 percent (IPv4 2,469 Gbps vs. IPv6 15 Gbps) of traffic exchanged is over IPv6

                              Based on the disappointing IPv6 adoption numbers, it seems like businesses are avoiding the new protocol because they believe the transition is too difficult. But in my professional experience preparing for IPv6 is actually quite simple.

                              Service providers

                              Network service providers who already have an IPv4 allocation from ARIN will find it is easy to get IPv6. All you need to do is apply for an IPv6 allocation, and the process is usually far less complicated than applying for an IPv4 allocation because different policy requirements apply. For example,  instead of the rigors of justifying each subnet as small as a /29 from your current IPv4 assignments, like you would if you were applying for additional IPv4 addresses; your IPv6 allocation size is determined by the number of geographically diverse locations your network has for an end user. Once you provide ARIN that information, you can be allocated a minimum of a /32, or 79 decillion (yes, that’s actually a real number) IP addresses.

                              Once you have IPv6 addresses, adding them into your existing network is astonishingly easy in most well-engineered networks.   Most tier 1 and tier 2 carriers offer\ native IPv6 transit services and will have no problem accommodating your BGP announcements.  Adding IPv6 into your IGP is also very simple.  OSPFv3′s configuration syntax is nearly identical to OSPF’s on both Cisco and Juniper equipment.  Running OSPF and OSPFv3 in parallel is uncomplicated.  The case is the same for IS-IS.  A lot has been written about how to add IPv6 to your network.  IPv6 implementation will vary depending on your infrastructure, so there’s no one “right” way. But a quick Google search for “IPv6 IGP” should yield a lot of useful results, including many from popular hardware vendors.  Once you receive your IPv6 allocation, it should only be a matter of days before you can start offering IPv6 services.

                              IPv6 at home

                              For end users, adoption has been negligible.  Understandably, this is the slowest market to adopt IPv6 – even though it’s the market that needs it the most. The disappointing statistics with regards to IPv6 adoption on the Alexa Top 1000 seem to bear out the perception among uninformed end users that parts of the Internet will become unreachable to them. In actuality, 6to4 gateways will ensure they can communicate with IPv4-only networks. Fortunately for savvier home consumers, Comcast, the largest eyeball network in the US, has started rolling out IPv6 to those users who want it. Comcast customers can log onto to find out whether their areas support IPv6, and how to enable it.

                              What Can I Do?

                              Petition your cable and DSL provider to adopt IPv6.  They likely already have a plan in place to adopt IPv6, but it may not be a priority if there doesn’t seem to be much consumer demand.  Inform them that ARIN only has 25 million IPv4 addresses left. That works out to just one IPv4 address for every 7.88 Americans, and doesn’t count Canada and many parts of the Caribbean, which are also served by ARIN. The time to act is now.

                              Petition your hosting provider to add IPv6 support, or find an alternative provider.. Rackspace, for instance, assigns every new VPS an IPv4 and an IPv6 address by default, and their cloud-based hosted DNS service also supports quad A records.

                              Finally, you can join me and become an IPv6 evangelist. There are many IPv6 readiness and awareness websites.  Find out how you can become involved in the IPv6 awareness community and help push the Internet’s transition forward. IPv6 is inevitable, but it won’t be pretty without our effort.
