This code used to return my local ip address as 192.xxx.x.xxx but now it is returning 127.0.0.1 . Please help me why the same code is returning different value. Is there something that I need to watch at linux OS.

import java.util.*;
import java.lang.*;
import java.net.*;

public class GetOwnIP
{
  public static void main(String args[]) {
    try{
      InetAddress ownIP=InetAddress.getLocalHost();
      System.out.println("IP of my system is := "+ownIP.getHostAddress());
    }catch (Exception e){
      System.out.println("Exception caught ="+e.getMessage());
    }
  }
}
