[44net] Odd DNS Issue

All, I'm wondering if anyone else has seen this issue. I'm running BIND version 9.9.5 at 44.60.44.3. I just recently upgraded from 9.8 because I thought it would solve a very weird issue that I'm experiencing. I allow all to to lookup 44.in-addr.arpa and ampr.org; and it works. BUT, some reverse records always time out. So far, I have tested the following IP addresses which have PTR records, but do not produce results: 44.102.1.1 44.102.1.2 44.108.1.1 44.108.1.2 44.108.1.3 44.60.44.1 44.60.44.2 44.60.44.3 44.60.44.6 44.60.44.7 The only pattern that I've discovered when a lookup times out, is that the fourth octet is always less than 10. I've checked the system log, and there is no denial for the DSN query. I was wondering if anyone had ideas/suggestions. Thanks and 73, Lynwood KB3VWG
