[6bone] AAAA and A6 recent status?

[Todd T. Fries]

A6 and/or DNAME both cause 'unknown record type' style errors with bind4,
and older bind8 (newer bind8 can deal with A6 and/or DNAME) ..

The problem stems from the fact that prior to current bind8/bind9 .. there
was hardcoded a list of valid RR types in the dns servers.  A6 and DNAME both
add a new 'type' that is unknown, therefore invalid to older dns servers.

| All your slave servers have to at least be able to serve A6 RRs.
