That doesn't compute considering all the XP machines with Teredo addresses
that asked for my AAAA only content.
"Of the users getting v6 only gif from non-tunnel-space, 58% were from
Proxad (free.fr I believe), and then on the list came UNINET, SUNET, FUNET
(university networks in .no, .se and .fi) and Hurricane electric.
98% of Teredo users run Windows XP.
88% of 6to4 users run Windows Vista."
So 98% of Teredo users getting the v6only content (using DNS) was using
WinXP, so it does seem it does AAAA lookups.
