Perhaps you should take a look at Dns.GetHostByAddress(), it takes a string (ip address) as a parameter and returns a IPHostEntry, from which you can get the host at the HostName property:

string host = Dns.GetHostByAddress("192.168.0.15").HostName;

P.S. I didn't test this, just browsed the documentation ;)

thanks a lot for your attention..
it works..but this method in framkwork 2.0 is out of date
is there any new methods??

Oh yes, sorry about that.
.NET 2.0 have the Dns.GetHostEntry() method that should do the same.

It is a good method: Dns.GetHostEntry()

The Method is interesting but it didn't work for me in this case
when I get the HostName it gives me the IP Address Again!!

i used winSock APIs instead and it just worked

anybody has an idea about this?

Need to download code?
