Why would 216.136.44.104 do something like this? 14 ip104.44.136.216.in-addr.arpa (216.136.44.104) [AS 4323] 404 msec 400
;; QUERY SECTION: ;; 104.44.136.216.in-addr.arpa, type = ANY, class = IN ;; ANSWER SECTION: 104.44.136.216.in-addr.arpa. 1D IN PTR ip104.44.136.216.in-addr.arpa. ;; QUERY SECTION: ;; 44.136.216.in-addr.arpa, type = SOA, class = IN ;; ANSWER SECTION: 44.136.216.in-addr.arpa. 1D IN SOA ns1.inc.net. hostmaster.inc.net. ( Umm.. because hostmaster () inc net 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
