Hello,

I'm new to operating a website and I'm leasing a virtual private server
(VPS) from GoDaddy.   I'm paying for cPanel / WHM as well.   It's running
CentOS 6.8 Final.  I'd like to setup reverse DNS but I'm having trouble.
I'm not 100% sure how to do it.   I have my hostname, franklin.jetbbs.com
and there's two IP addresses assigned to that hostname, 104.238.117.105
and 132.148.11.44.   I was trying to setup a round robin kinda thing but I
don't think I set it up correctly.

Anyway, I have ns1.jetbbs.com which has the IP of 104.238.117.105   and
then I have ns2.jetbbs.com that has the IP address of 132.148.11.44.   I
wanted to know if someone could look over what I have so far and let me
know if it's correct and how I should proceed.

So, in the /var/named directory, I create a file
called: 0.117.238.104.in-addr.arpa

The contents of 0.117.238.104.in-addr.arpa are as follows:
$TTL 1D
@       IN SOA  ns1.jetbbs.com. spork.jetbbs.com. (
                                        2016071705      ; serial
                                        1D              ; refresh
                                        1H              ; retry
                                        1W              ; expire
                                        3H )            ; minimum

0.117.238.104.in-addr.arpa.        IN      NS      ns1.jetbbs.com.
0.11.148.132.in-addr.arpa.         IN      NS      ns2.jetbbs.com.

104     IN      PTR     franklin.jetbbs.com.
44      IN      PTR     franklin.jetbbs.com.


Does that look correct?   If not, how should I change it?   If so, what's
the next step?   Thank you for your help!

Sincerely,
Ken
