( Umm.. because [email protected] was feeling lazy? ;) It isn't the first time I've seen people do this. However, usually they manage to have the PTR point at something that itself has an A record that matches. Alas, there isn't an entry: ip104.44.136.216.in-addr.arpa. IN A 216.136.44.104 I suppose given the sorry state of the REST of the PTR map, we should be glad that at least they acknowledged that they own the IP, and that it didn't give NXDOMAIN on the PTR ;) Valdis Kletnieks Operating Systems Analyst Virginia Tech
