Reverse DNS lookup

I have a block of 64 IP address and last week I had my ISP make us the Name server for that block. We have a bind server running... But we are doing something wrong. I cant resolve my name servers IP address to its host name. And when I do a DNS transversal it come back saying that there is no PTR record. I am pretty much green at this stuff, but I HAVE to figure it out... Our customers have email account with us, and sense the change email are not comming through... if you think you might be able to help just ask me for the information you need and I will ether post it or PM it to you. I am pretty sure I am doing somehting wrong in my records file. My syntax or something. Its just we have a block o IP's so I am not sure if I should use the cidr notation.

192/26.x.x.x.in-addr.arpa

or if I should just point it at the server or just use the network

x.x.x.in-addr.arpa

I dont know any input would be great


Thanks

Hello,

first I think you should learn more about RFC2317. This is what you need. Your reverse zone should look something like this: 192-255.x.x.x.in-addr.arpa.
The owner of /24 class should add some CNAMES that points to your /26 class.

Example: I have 81.181.24.0/26 class.
dig -x 81.181.24.1

I see SilentRage explained that very good.
