Build BIND rDNS Zone

This tool will generate a BIND Zone file for a reverse DNS delegation from a list of IPv6 addresses and a list of matching host names. The other information for the Zone header (Start of Authority - SOA) has intelligent defaults. The reverse DNS zone will use nibble format. Nibble format is a dot-separated reversal of all the hex digits in the expanded IPv6 address and allows greatly improved delegation of Reverse DNS at the expense of human usability of zone files - hence this tool.
