If you mean you want to know the IP address of the client who has logged-in to the server, gethostbyaddr() is not what you want to use.

If you have written your own application, when it calls accept(), the remote IP address will be returned as one of the parameters from accept() - see "man accept" for more on that.

If you have an application that has simply been handed a socket descriptor - say as its standard in (stdin) then you can try getpeeraddr() which will return the remote IP address associated with that socket.

If you mean to try to do somethine else, we'll need more details.
