IP address translation?
 

I’m looking for a program or for some command that allow translating the domain name to IP address. For example, I want to enter the www.ars.com === 255.255.255.255(the ip address).

for an easy way to do it then do a

I have a c++ program on my puter somewhere that does what you are asking. I'll see if I can locate it and paste the code here.

/*
** 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");
exit(1);
} if ((h=gethostbyname(argv[1])) == NULL) { // get the host info
herror("gethostbyname");
exit(1);
} 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.

host 1.2.3.4
host www.example.com

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

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

How about using either one of the programs nslookup, host or dig. -mk
