Live Beyond Layer 3

by

I’m a layer three guy, which means that I am a network guy, specifically an Internet guy. I work on routers and connect big networks to other big networks to try and make the Internet work better. For a long time, I, and many people like me have tried very hard to ignore what we call layers 8/9/10 (the financial, administrative, and governmental entities involved with the Internet). Or worse, sometimes we have been known to sneer at them as “damage to be routed around”. I know that attitude still persists among some, but it really fails to take in the whole story.

IETF 90 Part 2: IPv6 reverse DNS

by

Some thoughts on IPv6 reverse DNS. Lee Howard was speaking in the Sunset4 working group at IETF 90. He mentioned something that got me thinking. I have often discussed in my talks problems in IPv6 that were unanticipated. A lot of these problems are unintended consequences of very large subnet sizes. Some problems are outlined in RFC 6583. Lee mentioned another interesting problem, reverse DNS. Best practice [RFC1033] says that every Internet-reachable host should have a name (per RFC 1912) that is recorded with a PTR record in the .arpa zone. It also says that the PTR and the A record must match.

IETF 90 Part 1

by

ARIN Advisory Council member, Cathy Aronson, is at IETF 90 in Toronto, Ontario, Canada this week. Follow along as she shares her findings with us on TeamARIN! Yesterday morning I attended the IEPG (Internet Engineering and Planning Group) meeting here at IETF 90. George Michaelson of APNIC gave an interesting presentation about Teredo (a tunneling technology that allows IPv6 capable hosts to use IPv6 over a IPv4 only connection). George’s slides are here. The great thing about his presentation is that he observed Microsoft doing exactly what they said they were going to do. They turned off their Teredo relays. It is clear in George’s graphs that the Microsoft Teredo relays have been turned off. The presentations about sunsetting Teredo are linked here:

ARIN is in the Caribbean

by

See what we did there? Not only are the letters A-R-I-N actually in the word cARIbbeaN, but so much more. There are many Caribbean economies in the ARIN’s service region and we work hard to serve everyone that depends on us for Internet number resources. For those of you in the Caribbean, we have some suggestions for what you can do to prepare for the future of the Internet and to get more involved in ARIN and other important organizations in the Caribbean. Get ready for IPv6. Network operators and content providers alike need to prepare for the future Internet.

Should you attend an ARIN on the Road event?

by

For the past four years, ARIN has hosted a series of one-day educational events to provide the ARIN community with opportunities to meet and discuss issues ranging from our technical services to public policy for Internet number resources at a location near them. The program is designed to bring new faces and voices into ARIN deliberations such as policy discussions, providing feedback on our services, or growing the number of members participating in ARIN governance.

Interop Las Vegas: Doubling Down on IPv6

by

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.
