    I'm curious how people are configuring Reverse DNS. There aren't really any features for this in WHM, but occasionally we are getting registrars who want reverse DNS entries.

    Any suggestions?

    If you need to configure reverse dns you must do it manually. Just add the new in-addr.arpa master zone for the ip. There is already one in /var/named that you can copy and change the ip on. Then add the zone file into /etc/named.conf. Again there is already a sample in the named.conf file that you can copy for your new ip/zone.
    Cheers;

    Keep in mind that one of the best books you could purchase as a sys admin is that O'Reilly DNS & Bind book- It reads like a trig book, but as a reference, you can't get much better.

    ALSO keep in mind that your upstream provider (whomever it is that handed you your IP addresses), will need to delegate reverse authority (propagate the IN-ADDR-ARPA zone), to YOUR primary nameserver, on your range of addresses. Then, you can spread the love (delegate reverse yourself), through your IP range to your own customers.

    It starts at the top though- make sure that whomever dealt you your IP addresses delegates this ability to the nameserver(s) of your choosing.
