April 2008 Archives

I just got back from the Spring '08 Internet2 Member Meeting. Internet2 has routed IPv6 across their backbone since 2001, but until recently they hadn't enabled it on their services (dns, www, mail, etc). In recent weeks, that's started to change.

In the past, Internet2 has IPv6 enabled only on a few test machines (their CoManage SP and InCommon's IdP). At the Member Meeting, they enabled IPv6 on one of their authoritative DNS servers (dns2.internet2.edu). They plan to v6-enable their other authoritative server next week. And they're talking about v6-enabling their incoming mail server in a few months. Oh, and the Internet2 IPv6 Working Group home page is now reachable over IPv6.

In the closing session, Internet2 invited John Curran, the chair of ARIN, on-stage to discuss the need to transition to IPv6. You can get his slides or watch the video of his talk (it starts at 17:40).

So congrats to I2 for starting to use (as opposed to just route) IPv6.

Now if they could only get reverse DNS setup....
At the beginning of 2008, I made a blog post asking how many of the top-level domains (.com, .uk, etc) had authoritative nameservers which were reachable over IPv6. In January, 2008, there were 181 v6-reachable domains.

I re-ran the analysis this afternoon to see how things had changed in four months. Eight more domains are reachable over IPv6. This means that 70% of top-level domains have at least one IPv6-enabled authoritative server.

Here are the additions:

.arpa
.az (Azerbaijan)
.do (Dominican Republic)
.eg (Egypt)
.eu (European Union)
.km (Comoros)
.mk (Macedonia)
.mz (Mozambique)
.sa (Saudi Arabia)
.sz (Swaziland)

Sadly, the .td (Chad) domain servers is no longer reachable over IPv6.

Interestingly, despite the much-discussed US federal IPv6 mandate, the nameservers for .gov and .mil are still not reachable over IPv6.

I also looked at IPv6 DNS in US higher education. At the top level, Educause has still not seen fit to IPv6-enable the .edu servers. In January, 2008, there were only 12 Universities with IPv6-reachable DNS. Four months later, six more US universities have IPv6-enabled their nameservers:

  • Georgia Institute of Technology (new)
  • Indiana University
  • Ohio University (new)
  • Pennsylvania State University
  • Princeton University
  • Portland State University (new)
  • University of California, Berkeley
  • University of California, San Diego
  • University of Delaware
  • University of Illinois at Urbana-Champaign
  • University of Iowa (new)
  • University of Notre Dame
  • University of Oregon
  • University of Pennsylvania
  • University of Rhode Island (new)
  • University of South Florida
  • Wichita State University
  • Worcester Polytechnic Institute (new)
This brings the total to 18 of the 212 University members of Internet2.

Wikipedia and Mediawiki.org have IPv6-enabled their mail servers. Also, the MediaWiki bug tracker is IPv6-enabled.

Welcome to the IPv6 internet!

By the way, I noticed this in a discussion in #ipv6 on FreeNode. I was using an IPv6-enabled IRC client and an IPv6-enabled IRC server.
