What will I see if I do this at my server teminal dig +nssearch my.ser.ver.ip.in-addr.arpa Should this command sow my server IP if so, my server is not doing that. My server has rDNS when I did this 123.123.123.123 321.321.321.321.in-addr.arpa I got system is the owner.

  To see your server principle IP address use dig your.server.name A
  The command you have given is for resolving the nameserver SOA records : and should be given with 'your.server.name' and not the in-addr.arpa IP address. To reverse dig to get a PTR record usedig -x xxx.xxx.xxx.xxx
  where xxx.xxx.xxx.xxx is your server IP For full information Google for man dig, or try that in a terminal (terminal results may vary dependant if your system has the related manual installed)

  I'm guessing it came from How to Configure Reverse DNS for BIND in WHM - cPanel Knowledge Base - cPanel Documentation or Configurar DNS inverso para BIND en WHM - cPanel Knowledge Base - cPanel Documentation

  If that is indeed where it came from the response should indicate the Authoritative Nameservers for the IP address. It should also be noted that the PTR should be present and resolvable and the IP address should be the IP address listed backwards as it is configured in the PTR record. +[no]nssearch When this option is set, dig attempts to find the authoritative name servers for the zone containing the name being looked up and display the SOA record that each name server has for the zone.
