I see.  Well, perhaps some kind of "don't do AAAA lookups" runtime
config would help such people.  Or a switch to accept replies from the

I wonder how many people are suffering from this - it's not clear that
it's sensible for people who aren't having the problem to spend time
working on it, compared to replacing a few broken routers.
