Usage

From source file:Main.java

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

    byte ttl = (byte) 1;

    byte[] data = "Here's some multicast data\r\n".getBytes();
    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));
