Get all the IP Addresses to Which a Device is Exposed

At times, your device can be exposed using multiple interface cards. The following code sample will help identify various interfaces and the related IP configuration available on them.

import*;import java.util.*;public class NetworkInterfaceIPs {   public static void main(String args[])   {      NetworkInterfaceIPs networkInterfaceIPs = new NetworkInterfaceIPs();      networkInterfaceIPs.proceed();   }   private void proceed()    {      try      {         Enumeration networkInterfaces = NetworkInterface.getNetworkInterfaces();         InetAddress inetAddress = null;         System.out.println("Available IPs in NetworkInterface.");         while (networkInterfaces.hasMoreElements()) {                NetworkInterface networkInterface = (NetworkInterface) networkInterfaces.nextElement();                Enumeration inetAddresses = networkInterface.getInetAddresses();                            while (inetAddresses.hasMoreElements()) {                    inetAddress = inetAddresses.nextElement();                    if (inetAddress instanceof Inet4Address) { //Working on only IPv4 IPs                  System.out.println("IP: " + inetAddress.getHostAddress());                    }                               }            }               }catch(SocketException se)      {         System.out.println("SocketException: " + se);      }   }}/*

Expected output:
