By using gethostname & gethostbyname you can get a machine's IP address, but on some machines, it seems to give the loopback and on some, the actual IP (well, the loopback is a valid IP I suppose, but you know what I mean). Maybe this is attributed to the /etc/hosts file (in Linux)? In any case, is there a way to ensure you're getting back the actual machine IP as opposed to the loopback? Is there a way to test for multiple IPs on a machine?
That is a viable option, and thank you. That said, is there a way do this without using sockets? I'd rather not add socket stuff in there if it is used only to find the IP (unless it's necessary).Quote:

Once you have a connected socket, you can do;
You might try having your program run /sbin/ifconfig, then dissecting the output for the IP. Should just be a matter of finding the substring.
This would help also if a machine was connected on more than one network (like a router, or a wireless laptop that happened to also be plugged in)
