It looks like one of nanog's outbound servers doesn't have a PTR record.

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

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/ records you setup a cryptographically strong authentication first. Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org
