XP won't ask for AAAA unless it has non-Teredo connectivity though I don't think.
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.
I mean non-Teredo connectivity in addition to Teredo. Perhaps they have Teredo and 6to4, and could not reach you via 6to4 so instead used Teredo, or, any number of scenarios. -- Nathan Ward
