Marshall Eubanks writes, in response to Jordi's "8% IPv6" anecdote:
These estimates seem way high and need support. Here is a counter-example.
While I'm also skeptical about the representativeness of Jordi's estimates, this is a bad counterexample (see below about why):
Sorry for the late response, but I got some numbers in Japan. (1) httpd access logs of www.kame.net In 24-hour access logs on September 13, there are 148 unique IPv6 addresses within 1,849 unique IPv4 and IPv6 addresses. So, about 8.0% is IPv6. The breakdown of IPv6 address blocks: 2001::/16 127 2002::/16 9 2400:2000::/19 1 3ffe::/16 11 If we remove 528 addresses from Yahoo! Slurp and Googlebot, the IPv6 ratio becomes 11.2%. Obviously, this site is biased for IPv6 users but Jordi's number isn't far off. (2) traffic growth at an experimental IPv6-only IX in Tokyo We have updated the traffic graph of NSPIXP6 at http://www.wide.ad.jp/nspixp6/traffic.html The traffic volume of IPv6 is still about 1/1000 of IPv4. The IPv6 growth rate has slowed down a bit for the last 12 months. -Kenjiro
