I'm not sure when it happened, but right now I'm getting the web page
dual-stacked as well,

anticimex at hsa:~$ host www.youtube.com
www.youtube.com is an alias for youtube-ui.l.google.com.
youtube-ui.l.google.com has address 74.125.39.102
youtube-ui.l.google.com has address 74.125.39.113
youtube-ui.l.google.com has address 74.125.39.138

I tried firewalling away my IPv4 connectivity and used a non-local,
dual-stacked, DNS resolver to browse the page and it sort-of works.
Front page looks kind-of stupid (some elements missing), but it is
possible to view videos, etc. :)

When using a local resolver the DNS fails however, as expected.
Isn't end-users having local resolvers something to expect in the
future, with DNSSEC and all? It's not a rhetorical question. I actually
want to know, since this affects the degree to which dual-stacked /
single-stack-v6 DNS support will be required to serve future mobile
v6-only users, or what not.

So you IPv6 ninjas over at Google, what's next? :)
Achieving support of single-stack IPv6 users should be the long-term
goal, I presume.
Dare you answer at all re: the DNS infrastructure? :)

Big thanks,
