Since you can't query DNS for "give me A+AAAA", the application query
"give me whatever address you have!" will result in two DNS queries, one
for A records and one for AAAA records.  Two queries, two packets, two
responses (possibly with 0 answer records in them, if no A or AAAA record
is available).

Querying for "ANY" doesn't work.
