Unless I'm missing your point, bind 8.2 does not exhibit this behaviour. Your own master zones are accepted. Tested with bind 8.2 and "fake" master zones for test.com and 1.192.168.in-addr.arpa. capistrano.beach.net # what /usr/sbin/named | grep named /usr/sbin/named: named 8.2 Tue Mar 23 11:23:34 PST 1999 danat_private:/usr/home/dan/bind8.2/src/bin/named capistrano.beach.net # nslookup www.test.com Server: ns.beach.net Address: 206.16.184.129 Name: www.test.com Address: 192.168.1.1 capistrano.beach.net # nslookup 192.168.1.1 Server: ns.beach.net Address: 206.16.184.129 Name: www.test.com Address: 192.168.1.1 www.test.com is, in reality, 207.206.9.99 Apologies to Test.com, Inc., I've given you your zone back :) Now, if you have a zone like (note only two octets, 192.168) zone "168.192.in-addr.arpa" { type master; file "db.192.168"; }; It's not going to be used to directly look up 192.168.1.1 192.168.1.1 is in the zone 1.168.192.in-addr.arpa so your lookups will fail, but it's not due to a bug in bind.
