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

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

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. (
            38400 )
57.196.65.in-addr.arpa.    IN    NS    dns1.troycorp.com.    IN    PTR    smtp2.troycorp.com.    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 This is the file in /var/named. It is also referenced in /etc/named.conf as the above name....

Any insight would be appreciated...


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

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,  IN  PTR   ftp.troycorp.com.

Needed to be,  IN  PTR  ftp.troycorp.com.

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