This is happening because of the way BIND 9 handles the presence of AAAA
records in the glue data. May TLDs, including recently both com and net,
have AAAA records now.
The problem will be fixed in 9.3.1 when it is released. Meanwhile, those
who have only IPv4 connectivity can solve the problem by putting -4 in
their named_flags in /etc/rc.conf[.local].
