Oops, fixed. The machines were moved to a new a subnet this morning and I was so preoccupied with remembering to create the ip6.arpa PTR records that I completely forgot the in-addr.arpa's. Bet that's a first. I suppose it's progress to be thinking about v6 first and v4 second. -Larry Blunk Merit

It will be much better when the OS's just register themselves in the DNS. Humans shouldn't have to do this when a machine renumbers. Named can already authenticate PTR updates based on using TCP and the source address of the update. For A/AAAA records you setup a cryptographically strong authentication first.
