[dns-wg] AAAA lookup misbehaviour

I do have some fingerprinting results, but they were a very
simple-minded application of fpdns. I'm sure the fpdns authors could
do a much better job (in fact, asking for unknown or rare types is
probably a useful fingerprinting technqiue).

The WG cooperating with the vendors/operators would also be good,
as they can then be a part of RIPE efforts to encourage/smooth IPv6
deployment. I'd certainly be interested to see a case study from a
(certain) big operator describing the deployment of a fix. OTOH,
it may be sufficient to document the problem so it can be more
easily diagnosed and fixed by vendors and operators who trip over
it.

(I presume DNSSEC may run into similar problems with weird responses
for unknown types, but I am rather ignorant of the details of
DNSSEC.)
