    I started getting IPs from ARIN directly, instead of the data center I'm colocated at. Now I have to start applying rdns myself for my clients upon request, instead of having the NOC at the DC do this. That is obvious, since I am in full control over the IP delegation and therefore have nameserver authority.

    The question is, how do I "create" ptr / rdns records for my clients?

    My current server uses Cpanel / WHM with ns1/ns2.mycompany.com

    I also applied those as dns nameservers in the ARIN IP's whois record.

    How do I create rdns for my clients? Should I install Cpanel DNS Only on a entirely separate server and use this method instead?

    Downloads - cPanel Inc.

    If so, how can I seamlessly transition over the dns records to that new dns server, retaining my ns1/ns2.mycompany.com and their ns1 and ns2 IP addresses?

    Even more important: I have to change the ns1/ns2 IPs to the new ones I retrieve from ARIN. How can this be done, avoiding downtime during the dns transition?

    Is CPanel DNS Only free? I could not find any pricing info.

    Thanks.

    I installed cpanel dns only.

    I do not see any add dns option in whm

    Can someone explain easily how to add rdns records for clients, especially in bulk quantity?

    i don't think, cpanel come with reverse dns template to add one, but you can easily create reverse dns zone for your ips .. you can find more info here
