You must also make sure that your ISP has delegated you the 12.195.122.240/28 subnet. You can read the rfc2317 for classless IN-ADDR.ARPA delegation here |
Right, That would be the correct syntax if I was hosting the whole class C block.
Here is a dig +trace:

After reading
This I settled on the following configuration.:
Here is my named.conf entry for the zone:
Code:
zone "240/28.122.195.12.in-addr.arpa" {
type master;
file "/var/named/12.195.122.240_28.rev";
};
This is what is contained in the file 12.195.122.240_28.rev:
Code:
$ttl 38400
240/28.122.195.12.in-addr.arpa. IN SOA ns.bigview.net. jdappert.gmail.com. (
1229105748
10800
3600
604800
38400 )
240/28.122.195.12.in-addr.arpa. IN NS ns.bigview.net.
240/28.122.195.12.in-addr.arpa. IN NS ns2.bigview.net.
243.240/28.122.195.12.in-addr.arpa. IN PTR mail.netjax.com.
After applying these settings i visited
AOL's reverse check and boom, success!
I think one of my problems must have been that I had overlapping entrie and was generating a SERVFAIL.
Cheers
