** getip.c -- a hostname lookup demo
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <netdb.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

int main(int argc, char *argv[])
struct hostent *h; if (argc != 2) { // error check the command line
fprintf(stderr,"usage: getip address\n");
} if ((h=gethostbyname(argv[1])) == NULL) { // get the host info
} printf("Host name : %s\n", h->h_name);
printf("IP Address : %s\n", inet_ntoa(*((struct in_addr *)h->h_addr)));

return 0;

I didnt write the code. I got it from a tutorial site about network programming. Beej's site or something like that.

Will do both forward (domain name to IP) and reverse (IP to domain name) lookups.

Or you can use traceroute and even get all hops in between with hostnames and ip addresses
