In article <a8e99b8e-101e-7516-8af6-f8c1ffe436b8@time-travellers.org>; you write:

That seems reasonable, but since the point of 8482 was that ANY
queries to authoritative servers are at best silly, it hardly matters.

PS: I'm also coming to the conclusion that if you think DNAME solves
your problem, and your problem isn't the arcane IPv6 rDNS renumbering
for which it was invented, you don't understand DNAME.
