dubkat@stargazer ~ $ host ipv6.google.com
ipv6.google.com is an alias for ipv6.l.google.com.
ipv6.l.google.com has IPv6 address 2001:4860:b009::67
ipv6.l.google.com has IPv6 address 2001:4860:b009::63
ipv6.l.google.com has IPv6 address 2001:4860:b009::6a
ipv6.l.google.com has IPv6 address 2001:4860:b009::69
ipv6.l.google.com has IPv6 address 2001:4860:b009::68
ipv6.l.google.com has IPv6 address 2001:4860:b009::93

"www.google.com" should also report one or more ipv6 addresses
so that urls such as gmail, images.* etc also work with ipv6
without /etc/hosts hackery. This would make for more transparent usage.

What version of the product are you using? On what operating system?
GNU/Linux 2.6.31 and Windows 7

This is already implemented, but only for users behind DNS resolvers which have 
been 
enrolled in the "Google over IPv6" program:

http://www.google.com/ipv6

If your ISP isn't enrolled, then ask them to deploy IPv6 and enroll.  Failing 
that, 
you can get DNS service from one of the major tunnel brokers.  I believe 
HE.net, 
SixXS, and gogo6 all provide DNS resolvers.
