if all you've got is a hammer, every problem looks like a nail.  so, the
above problem statement looked like a dns issue to me, and to some other
folks, and thus was born A6.  had ietf killed AAAA back when there were
effectively zero ipv6 hosts on the 'net, and paid the apparently-high A6
complexity penalty, we'd be talking about something else by now.  as it
is, the shim6 complexity penalty is even higher, and i don't think we'll
ever get to stop talking about this problem.
