    Contact your provider/data center and have them configure rDNS (Reverse DNS) for you.

    Hey !

    If you do not control the IP delegation, and most servers do not have control of the IP as the IP provider does, then you cannot setup a PTR record for rDNS in WHM and have it work.

    The only way these zones can be setup and work will be when the IP provider delegates control of the IP to the server, which again is rare and only happens if your IP provider does confirm they've delegated the control to your machine.

    Please note that this thread is from 2005. There are far more recent discussions of PTR records and reverse DNS (rDNS). It is unlikely the original poster still is checking the forum for a response.
