hey the IP address of host computer can be achived by the InetAddress class.

You can do it by calling getByName() method with host name as parameter, it returns InetAddress object.

On this object you can call getHostAddress() method to get the IP address of the given host.


Java Code

package com.myjava.ip;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class MyIpByHost {

public static void main(String a[]){

try {
InetAddress host = InetAddress.getByName("www.java2novice.com");
System.out.println(host.getHostAddress());
} catch (UnknownHostException ex) {
ex.printStackTrace();
}
}
}
