There is an odd edge-case in dns. DNS_ERR_NOANSWER isn't actually a
great name.
Take the following example:
blah.blah.com exists as a TXT record, but not an IN A
If you query for IN A blah.blah.com, an RFC compliant server will return
a status of NOERROR without any records; because blah.blah.com exists,
just not IN A. There was an answer; a vaild answer.
I would say there should be another check here where the above situation
is checked for appropriately.
