Well we really want to get rid of A lookups. Why don't we just
recommend that we publish mapped A records in AAAA RRsets and have
master servers update AAAA RRsets if they are inconsitent with the
A RRsets.
We also need a way to signal that there are no A records in the
AAAA RRset. ::ffff:255.255.255.255 or ::ffff:0.0.0.0 would be
sensible records to indicate this.
That's a terrible hack and error prone to implement.
