Internal Working

This applet is adapted from Lars Kindermann applet and basically just use the Java Socket class to get the host address:

        try {
            String str1 = new Socket(str2, i).getLocalAddress().getHostAddress();
            if (!str1.equals("255.255.255.255")) obj = str1;
        } catch (SecurityException localSecurityException) {
            obj = "FORBIDDEN";
        } catch (Exception localException1) {
            obj = "ERROR";
        }
