Can somebody point me in the right direction to get this error fixed? I am on a Red Hat dedicated server running cPanel/WHM.


CODE
Location: United States [City: San Francisco, California]

Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 207.44.240.28 is found by looking up the PTR record for
28.240.44.207.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work for more information.

How I am searching:
Asking d.root-servers.net for 28.240.44.207.in-addr.arpa PTR record:
d.root-servers.net says to go to indigo.arin.net. (zone: 207.in-addr.arpa.)
Asking indigo.arin.net. for 28.240.44.207.in-addr.arpa PTR record:
indigo.arin.net [192.31.80.32] says to go to ns1.ev1servers.net. (zone: 240.44.207.in-addr.arpa.)
Asking ns1.ev1servers.net. for 28.240.44.207.in-addr.arpa PTR record: Reports ev1s-207-44-240-28.ev1servers.net. [from 207.218.245.135]

Answer:
207.44.240.28 PTR record: ev1s-207-44-240-28.ev1servers.net. [TTL 86400s] [A=None] *ERROR* There is no A record for ev1s-207-44-240-28.ev1servers.net. (may be negatively cached).


Can I add this A record myself to the DNS on my server?

make an A record like server1.domain.com. Then open a ticket, and ask that the reverse DNS for the ip, be set to server1.domain.com.

this error is because the A record for ev1s-207-44-240-28.ev1servers.net does not exist. But the reverse DNS on the IP points to ev1s-207-44-240-28.ev1servers.net.
