And you can add this one to your list:

DNS Server                    IP
212.27.40.240 (free/proxad)   2001:4860:A003:0:0:0:0:68

$ host -t AAAA www.google.com 212.27.40.240
www.google.com      	CNAME	www.l.google.com
www.l.google.com    	AAAA	2001:4860:A003:0:0:0:0:68

As you can see, no need for http://ipv6.google.com/ to reach Google
over IPv6 using default DNS resolver provided by some French ISPs.
www.google.com starts to be resolved as an IPv4/IPv6 website.
