I just got off the phone with ARIN after discovering some incorrectly delegated in-addr.arpa zones. We (Internet America) have 209.196.64.0/18 and all of a sudden reverses weren't working. ARIN mistyped a transfer yesterday and got the 2nd Octet wrong. Verado, Inc (NET-VERADO-DC26) VERADO-DC26 209.177.128.0 - 209.222.143.255 Verado, Inc (NET-VERADO-DC27) VERADO-DC27 209.177.160.0 - 209.222.191.255 Internet America, Inc. (NET-IA-CR-2) IA-CR-2 209.196.64.0 - 209.196.127.255 They have corrected the database, and the next zone load should fix it. I thought others in the NANOG community might want to know.
