Hi,

I found many utilities in the web or rather the internet to resolve ip
address and host names , i took this example

host name : mp3.box.sk whose IP was resolved to be 69.31.81.51

now i took the same ip and tried to resolve the host name, for my
surprise i found that to be
colo-69-31-81-51.pilosoft.com which is not mp3.box.sk for sure, can
anyone explain as to why this problem is caused?

If you need to have proper rDNS, you need to talk to your provider.

There isn't a one to one mapping from host names to IP. I have two
websites with two different domain names, but they're hosted on the same
server, and so resolve to the same IP.
