More C++ Questions - How to retrieve a host or ip from an ip or host?

Does anyone know how to retrieve a host from an ip in C++. Also, I need to know how to retrieve an ip from a host.

man socket.h

Also, for a very basic crash course in network programming check out http://en.wikibooks.org/wiki/Programming:C_Networking_in_UNIX

(But then again, you would probably be using c to do this ;))

The easiest way is to use

system("PING <IP/HOST> >> targetfile");

for example

system("PING www.google.com >> C:\\logfile.txt");

and then just read from the file since it will contain both the IP and the hostname.
