I set up the reverse zone at your suggestion. Here is the nslookup
Re: reverse dns
From: Steve Nowacki
Date: Wednesday, July 30, 2003
Time: 6:38:26 am
result:
% nslookup 12.33.161.78
Server: dns-rs2.bgtmo.ip.att.net
Address: 12.127.17.72
Name: ftp.knightprinting.com
Address: 12.33.161.78
Aliases: 78.161.33.12.in-addr.arpa
That is the result I expected, but I'm curious as to why the "Aliases:"
line shows up. nslookup on 63.230.107.197 returns:
% nslookup 63.230.107.197
Server: dns-rs2.bgtmo.ip.att.net
Address: 12.127.17.72
Name: mail.knightprinting.com
Address: 63.230.107.197
Should I remove or disable the reverse zone that I had originally set
up? Its name is 161.33.12.in-addr.arpa. and looks like this:
161.33.12.in-addr.arpa. NS ns1.arvidburns.com
161.33.12.in-addr.arpa. NS ns2.arvidburns.com
66.161.33.12.in-addr.arpa. PTR ns1.arvidburns.com
78.161.33.12.in-addr.arpa. PTR ftp.knightprinting.com
Or could I just set the PTR records in that original zone to match
those you listed for the new reverse zone and remove the new zone:
161.33.12.in-addr.arpa. NS ns1.arvidburns.com
161.33.12.in-addr.arpa. NS ns2.arvidburns.com
66.64/28.161.33.12.in-addr.arpa. PTR ns1.arvidburns.com
78.64/28.161.33.12.in-addr.arpa. PTR ftp.knightprinting.com
Bye,
Steve
