Thanks for mentioning rfc 4074.  The stuff in that document matches
the thoroughly broken behaviour of the IPv6 DNS resolver client of
Windows 2003 that I had encountered just recently.

IMO, rfc4074 exhibits a significant amount of cluelessness about DNS,
the "Full Standard" document maturity level, and the realities of
backwards compatibilities for an incredibly huge installed base.


The answer to the question "what can I infer from a failed AAAA lookup"
must be deduced from STD 13 **ALONE**, and it amounts to "very close to
nothing at all".

Now this puts the slow adoption of IPv6 into perspective if it takes
the IPv6 crowds >10 years to figure that one out,
