This is arguably missing the point of IPv6 day.
If you want to play with a v6 tunnel client, you can do this any day. You
simply point your browser at http://ipv6.google.com/ or
http://www.v6.facebook.com/ to see if it works.
However, the Internet migration strategy is dual-stack. There will never be
any requirement for users to install tunnel clients on their machines.
The fundamental reason for v6 day is to encourage *content providers* to
enable both v4 and v6 concurrently on their *well-known* URL (i.e. return
both AAAA and A records), and then see how many of their (non-v6) users are
broken by doing this. That would be users whose local v6 stack is broken,
or who are on a network which announces v6 connectivity when it doesn't
actually have it.
So, this is what's different for v6 day:
$ dig www.google.com aaaa
;; ANSWER SECTION:
www.google.com. 86094 IN CNAME www.l.google.com.
www.l.google.com. 218 IN AAAA 2a00:1450:400c:c01::93
Previously, you'd have got an empty response (and the client would then
look for an A record instead).
The hope is that this will give confidence to those websites to run both v4
and v6 permanently on their main URL.
