Revised Patch - Handles IPv6 labels/addresses

I borrowed the code idea in 6519 (but not an exact copy) to extend the lookups
into IPv6 zones.  Since this repeats code, we should probably have a
subroutine/function call for computing the reverse, but as we don't have that
yet, I'd let this code stand.

I noted in the regex for IPv6, we don't need 9 copies (but only 7) of the
latter term as permitting 9 would allow ANY representation where the lower 32
bits are represented as an IPv4 embedded address.  However, only two forms (in
"::/80") were ever defined - and at most, they would have 3 colons and 3 dots
(implying a maximum value of 6, but regular IPv6 addresses can have 7 colons). 
Therefore, 9 was lowered to 7 so as to exclude invalid representations.
