2001:4860:0:1001::68 points to the European cluster (in Amsterdam, as mentioned by berniv6 on #ipv6 in ipv6.chat.freenode.net) of ipv6.google.com, whereas 2001:4860:0:2001::68 (ipv6.google.com) is known to be located in US. My tunnel remote endpoint (2001:470:1f08:3b7::1|216.66.80.26) is located in London, UK. Notice the RTT ;)

As, you can see ipv6.google.com is resolving to an IPv6 address, and also I can connect to it :). karora on #ipv6 at irc.freenode.net told me that at Google, most of the IPv6 transition work has been done. So like sig_wall I also changed my /etc/hosts to point {mail,reader,www}.google.com to IPv6 address of ipv6.google.com, and to my surprise couple of google.com services worked but not orkut.com (I don’t use it :P)

abbe [~] chateau $ cat /etc/hosts |tail -1
2001:4860:0:1001::68 www.google.com mail.google.com www.orkut.com reader.google.com orkut.com ipv6.google.com

Anyways, happy IPv6ing….;)
