    DatagramPacket dp = new DatagramPacket(data, data.length, InetAddress.getByName("google.com"), port);

    MulticastSocket ms = new MulticastSocket(InetSocketAddress.createUnresolved("google.com", 8080));
    ms.joinGroup(InetSocketAddress.createUnresolved("127.0.0.1",8080),NetworkInterface.getByIndex(0));
    for (int i = 1; i < 10; i++) {
      ms.send(dp, ttl);
    }
    ms.leaveGroup(InetSocketAddress.createUnresolved("java2s.com", 8080),
