One thing we do need to do is to push more address state into the
DNS.  Today we just have AAAA records.

We want to able to map from address to names and names to addresses
as long as the mappings exist.

We also want to stop using deprecated addresses as soon as possible.

AAAA doesn't have enough information to meet both needs.  We can
remove deprecated address but then we loose the ability to map.

We can keep the deprecated addresses but then we don't preference
the non deprecated address when establishing new sessions.
