I saw one reference to preferred order of resolution being A => A6 => AAAA
which implies that A6 has a higher order of preference than AAAA. Also, the
DNS record type number for A6 is higher than AAAA, again indicating that
AAAA preceeded A6 in adoption.
In either event, as Ron states, there's no harm in covering 'em all.
