Yes, that is the solution which is currently discussed. Ideally
wand the following settings:

Query AAAA first, then A
Query A first, than AAAA
Query only AAAA
Query only A

I don't know that. But considering that some people get nervous when
ftp(1) reports that IPv6 doesn't work before it tries IPv4 it
might be good to have an option to look up A records first.
