I think it will be interesting when people start to look at the results. =
Following the delegation of someplace like a bank that has a financial =
interest in

a) security (ie: modern software)
b) people reaching their site

There's a lot of IPv6 brokeness in their services.

do "dig +trace aaaa www.citibank.co.uk"

You will eventually reach their load balancer dns servers that start =
giving out bad referrals/authority.

When you look at the top "25" broken sites, it quickly starts to look =
like something interesting.  The temporary failure shows some error in =
the resolver library looking for an AAAA record.  If you ask a non-bind =
nameserver you may have better luck as they seem to have relaxed SOA =
tracking.

Aside from the above, it does seem that there are a fair number of sites =
that have enabled IPv6 and gone without notice.

take www.informationweek.com which (from my view) sits behind AS209 with =
their IPv6 space, very similar to their v4 address.

I'm optimistic that more people will 'just enable' ipv6.  Hopefully =
other technical websites will do it as well, perhaps anyone that matches =
a regex of "ars" can influence the powers that be.  If they can get =
people to disable adblock, maybe they can serve up some AAAA as well. :)
