Hi,

I guess your dns server is running bind.
In this case, open the zone file of the x.y.z.in-addr.arpa zone and add your new PTR record. See this for an example of a reverse zone file example.
Then increase the serial number, save the zone file and reload bind.

Cheers

Hi,

Find the zone file for the 18.102.92.in-addr.arpa zone and add a record

Code:

163 IN PTR mailer.tek.com.

If you don't know the filename of the zone file, take a look in /etc/named.conf where it's defined.

The error you get (SERVFAIL), means that there is a configuration error. What is the outputof

Code:

dig -x 92.102.18.163

I guess you're running bind. If so post named.conf and the reverse zone file.
