.org gets to 100%

| | Comments (3) | TrackBacks (0)

Yesterday, the .org domain had a milestone: 100% of their namservers are IPv6-enabled. For several months, they had 80-some percent of their servers done, but last night, they v6-enabled the last one. .org is part of a small club of domains which have v6-enabled all of their nameservers:

  • .am (Armenia)
  • .asia
  • .bz (Belize)
  • .gi (Gibraltar)
  • .hn (Honduras)
  • .info
  • .lr (Liberia)
  • .mobi
  • .org
  • .tz (Tanzania)
  • .vc (Saint Vincent and the Grenadines)

These domains are well ahead of the other popular domains. Verisign publishes a quarterly report on the domain name registration business. Here are the most popular domains from their December 2008 report:

How do they stack up for IPv6 support?

Domain Percentage of nameservers with IPv6 glue
.de (Germany)33%
.uk (United Kingdom)36%
.cn (China)33%
.eu (European Union)20%

What about the "Other ccTLD" area? According to the report, here are the top ten ccTLDs (Country Code top-level domain):

Rank Domain Percentage of nameservers with IPv6 glue
1.cn (China)33%
2.de (Germany)33%
3.uk (United Kingdom)36%
4.nl (Netherlands)57%
5.eu (European Union)20%
6.ar (Argentina)13%
7.it (Italy)40%
8.br (Brazil)33%
9.us (United States)50%
10.au (Australia)50%

So, there's been some good progress, but there's a lot more to do. I expect to see many more domains get to 100% in 2009. I have automated scripts that check these statistics nightly, and there's been good progress during the year. Perhaps I'll post a more detailed entry in the future.

From here it looks like tld2.ultradns.net still lack AAAA.

Perhaps I have a caching issue. I'm seeing this:

$ dig -t NS +short org.

But it appears that the current list is:

It seems like the root servers are caching the old tld2.ultradns.net, check with:
dig -t NS +trace org.
