Question on properly setting up a reverse on a IP address...

[Jason]

Hello everyone.

Just wanted to clarify on the proper way to setup a reverse on a IP 
address. Since this particular IP address is going to be attached to my 
mail server and a lot of people require a proper reverse set, just want 
to make sure that it is correct.

If my IP address is

222.123.130.11

I should add something like:

11.130.123.222.in-addr.arpa

That would be the correct method?

Just verifying.

I appreciate your help.
