public class GetIP {

public static void main (String[] args) throws Exception {

/*

String s = InetAddress.getLocalHost().toString();

System.out.println(s);

String[] arr = s.split("/");

System.out.println("host name:\n" + arr[0]);

System.out.println("localhost IP:\n" + arr[1]);

*/

Enumeration e = NetworkInterface.getNetworkInterfaces();

while(e.hasMoreElements()) {

NetworkInterface n = (NetworkInterface) e.nextElement();

Enumeration ee = n.getInetAddresses();

while (ee.hasMoreElements()) {

InetAddress i = (InetAddress) ee.nextElement();

System.out.println(i.getHostAddress());

}

}
