I agree that using the v4 or v6 tag in forward or reverse is pointless.  One
can tell it is v4 or v6 by the result of the lookup and the hostnames don't
change just because they are accessible via IPv6.  If a hostname is directly
related to the fact that its IPv6 by all means put it in there though.
