How to know the ip address of an website??

Just create a file name IAdd.java write the following code:-

class IAdd{
public static void main(String a[]) throws Exception{
Socket s=new Socket(a[0],Integer.parseInt(a[1]));
InetAddress add=s.getInetAddress();
System.out.println(add);
}
}

now compile the code......
$javac IAdd.java

now run the code using following command................
$java IAdd [Host Name] [port number]
suppose you want to know ip address of http://www.google.com then the command will be given below:-
