Google is doing more experiments with IPv6. They now offer the option to selected ISPs to return AAAA records for queries coming in via IPv6. XS4ALL being advanced and always interested in new technologies is participating in this program. But: you have to resolve completely via IPv6 to get an IPv6 address. So I fiddled a little with the setup of bind to use the XS4ALL ipv6 resolver for queries regarding google:

zone "google.com" {
    type forward;
    forward first;
    forwarders {
        2001:888:0:6::66;
        2001:888:0:9::99;
    };
};

And now I get the cool answer:

koos@greenblatt:~$ host www.google.com
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 74.125.77.147
www.l.google.com has address 74.125.77.99
www.l.google.com has address 74.125.77.104
www.l.google.com has address 74.125.77.103
www.l.google.com has IPv6 address 2001:4860:0:1001::68

And the IPv6 instance of google will for example give me IPv6 cache links.
