It would be nice if dnswalk would check IPv6 AAAA records like it does for A records. And be able to check the PTR records for IPv6 as well. It looks like the NET::DNS module already has support for those v6 records so I would think that is half the battle. I'm not a very good Perl hacker, but because of the lack of tools for v6 I might have to take a shot at it.
