Find ip on my local machine

I am trying to find the ip of my machine, but all I get is the local
ip, not the ip I want. This is a program that finds the local ip, what
should be modified:

#include <stdio.h>
#include <netdb.h>

int main()
{
char hostn[400]; //placeholder for the hostname
struct hostent *hostIP; //placeholder for the IP address

//if the gethostname returns a name then the program will get the ip
address using gethostbyname
if((gethostname(hostn, sizeof(hostn))) == 0)
{
hostIP = gethostbyname(hostn); //the netdb.h function gethostbyname
printf("IP address: %s\n", inet_ntoa(*(struct in_addr
*)hostIP->h_addr));
}
else
{
printf("ERROR:FC4539 - IP Address not found."); //error if the
hostname is not found
}
return 0;
}

Off-topic for comp.lang.c, where we discuss the standard C language,
which knows nothing of IP addresses or anything else about networking.

I recommend you try a group specific to your platform. If you're
working on a Unix system, for example, try comp.unix.programmer.
