InetAddress in Networking

Inet Address encapsulates both numerical IP address and the domain name for that address. Inet address can handle both IPv4 and Ipv6 addresses. Inet Address class has no visible constructor. To create an inet Address object, you have to use Factory methods.

Three commonly used Inet Address factory methods are.

1. static InetAddress getLocalHost() throws UnknownHostException
2. static InetAddress getByName (String hostname) throws UnknownHostException
3. static InetAddress[ ] getAllByName (String hostname) throws UnknownHostException

Example using InetAddress class

import java.net.*;

class Test

{

 public static void main(String[] args)

 {

  InetAddress address = InetAddress.getLocalHost();

  System.out.println(address);

  address = InetAddress.getByName("www.netparam.com");

  System.out.println(address);

  InetAddress sw[] = InetAddress.getAllByName("www.netparam.com");

  for(int i=0; i< sw.length; i++)

  {

   System.out.println(sw[i]);

  }

 }

}

Output:
