If you are not behind a router, this code work well:
import java.net.*;
import java.util.Enumeration;
public static InetAddress getInternetAddress()
     try
          InetAddress address;
          for(Enumeration e1 = NetworkInterface.getNetworkInterfaces(); e1.hasMoreElements();)
               for(Enumeration e2 = ((NetworkInterface)(e1.nextElement())).getInetAddresses(); e2.hasMoreElements();)
                    address = (InetAddress)e2.nextElement();
                    if( !address.isLoopbackAddress() && !address.isSiteLocalAddress() )
                         return address;
     }catch(Exception e){}
     return null;
}
