Apologies if anyone thinks this does not require coordination or is somehow
not operational.
However, I have a situation where some nameservers for which I am=20
responsible
are receiving AAAA queries for hosts for which we are authoritative. We
return the SOA only as it seems we are supposed to, but, we are seeing a
significant delay before we get an A query back from the resolver, which,
we believe represents a significant delay for the end user in getting to
the web page in question.
Is there a better way to answer an AAAA query for a v4 only host? Is it
permitted and/or desirable to return a 6to4 or IPv4-Mapped address?
Is there some other preferable thing to return?
Thanks,
Owen
