Hey DNS Guru's look at this Zone..what's wrong!!

cyberkatis · Feb 18, 2003

Can anyone tell me why this reverse DNS Zone is not working. It resides on a Linux box running Bind 9.x.x.

$ttl 38400
57.196.65.in-addr.arpa. IN SOA dns1.troycorp.com. wilcoxc.troycorp.com. (
10
10800
3600
604800
38400 )
57.196.65.in-addr.arpa. IN NS dns1.troycorp.com.
74.57.196.65.in-addr.arpa. IN PTR smtp2.troycorp.com.
66.57.196.65.in-addr.arpa. IN PTR webcast.troycorp.com.

Worldcom delegated the /27 block from 64-95 to me. The also stated that the name of the file needs to be 64.57.196.65.in-addr.arpa. This is the file in /var/named. It is also referenced in /etc/named.conf as the above name....

Any insight would be appreciated...

The name of the file doesn't matter.

You normally should create reverse zone files for non-classful zones. This is the responsibility of the ISP because it's kind of tricky to do with subnets.

What's in the log when you reload BIND?? What does "does not work" mean??

Thanks for the help.

Turns out that I needed to put the classless subnet reference in the records....

So,
5.13.85.63.in-addr.arpa. IN PTR ftp.troycorp.com.

Needed to be,

5.0.13.85.63.in-addr.arpa. IN PTR ftp.troycorp.com.

and so forth.....when that was done it worked great.
