They do the same thing for requests that don't involve a CNAME, so they're
either choking on the AAAA query or a NOERROR response in general; it's hard
to tell which since I can only see one side of their box. I also don't know
how they react when you try to contact a site that _does_ have AAAA records,
since no major content site has them (which is a whole 'nother discussion).
What's weird is that they don't just return a 0-record NOERROR when you do
the follow-up A query, which would be the most logical failure mode -- they
return an authoritative answer of 0.0.0.1 instead.
Of course, dealing with idiot consumers on a regular basis, their tech
support folks insist the problem is on the user's machine and that it's a
bug in their v6 stack, despite Ethereal captures showing the bad DNS
response packets coming from their box...
