I am able to send UDP data to a specific ip address but I need to send it to who ever is listening on port 55555. here is the code I'm using. I do not want to send to a specific ip. 

```
import android.util.Log;

import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;

public class UdpServer implements Runnable {

    UdpServer() {
        run();
    }
    public void run() {

        try {

            String messageStr = "40320";

            int server_port = 55555;
            DatagramSocket datagramSocket = new DatagramSocket();
            InetAddress host = InetAddress.getByName("10.1.10.14");

            int msg_length = messageStr.length();
            byte[] message = messageStr.getBytes();
            DatagramPacket datagramPacket = new DatagramPacket(message, msg_length,host,
                    server_port);

            datagramSocket.send(datagramPacket);
        } catch (Exception e) {

        }
    }
}

```
