DNS problem

I kept receiving this mail from my server.
I believed, i configured something wrong for my DNS, however, i can use my domain fine.

Any idea what this error is about ? & how to fix it.
(i've changed the all the related info in bold characters)


thank you


IMPORTANT: Do not ignore this email.
The hostname (server.hub.com) resolves to . It should resolve to 12.236.95.156. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain.

Some are all of these problems can be caused by
/etc/resolv.conf being setup incorrectly. Please check this file if you
believe everything else is correct.


You may be able to
automaticly correct this problem by using the ' Add an A entry for your
hostname ' under ' Dns Functions ' in your Web Host Manager

 

Thank's for the reply

inside my /etc/hosts, i have
12.236.95.156 server.hub.com server 156.95.236.12.reverse.layeredtech.com 156
127.0.0.1 localhost
192.168.1.119 localhost.localdomain


Where should i enter A record for server.hub.com ?
I did that at my WHM


Thank's
