Reverse DNS - How Do I use it?

[64bithost.com]

So I have HSPC and I have a full class "c" license. I've been told that I can use my full class "c" license for reverse dns. As scooby doo says - "oh, Wassss That?" I have no clue. I looked it up on the internet and got various ideas on how to use my i.p range but am not sure as how to use my REVERSE DNS range...any help would be great
