What do you mean with "compatibility addresses"?  I don't know of
any such thing.

The ipv4 mapped ipv6 address is just a "hack" on the local
system.  You never see those "on the wire".

Anyway, what is the problem?  ipv4 and ipv6 can happely live on
the same network, it does so far a long time now.  Host just
support both ipv4 and ipv6 now.  If an application is written
properly, you shouldn't even notice the connection is over ipv4
or ipv6.
