IMO, we should just say "IPv6 addresses" (the critical thing here is the
size of the address -- no checks are done to validate them!), and nothing
about mapped addresses.

If some want to push mapped addresses in there, that's fine by me -- if 
your DNS resolver supports mapped addresses in /etc/resolv.conf (or 
equivalent).

No special code/text, is my opinion!
