Find the IP address of a server that you know, for example: google.com.
Java, as usual, provides a very easy mechanism to retrieve the IP address of a server that you know.
import java.net.*;
public class FindIPByName {
static String url = "google.com";
public static void main(String[] args) {
if (args.length == 1)
url = args[0];
try
{
System.out.println(InetAddress.getByName(url));
}catch(java.net.UnknownHostException uhe)
{
System.out.println("Unknown host: " + url);
}
}
}
/*
Expected output:
[root@mypc]# java FindIPByName
google.com/216.58.220.46
[root@mypc]#
[root@mypc]# java FindIPByName Oracle.com
Oracle.com/137.254.120.50
