Finding who sent the OSC message.

Hi, I am working on a project where we are using OSC on some devices to trigger functions and set variables in Unity.

I realize this is a long shot as it is only slightly unity related and not sure how many people got into this but I got this script working pretty well from someone who made it available.

The problem is that I do not know which device the call is coming from and I am not sure how to identify it.

This is the code that listens on the socket.

 using UnityEngine;
 using System;
 using System.Threading;
 using System.Collections;
 using System.Collections.Generic;
 
 using OSC.NET;
 using System.Net;
 using System.Net.Sockets;
 
 public class UnityOSCReceiver : MonoBehaviour {
     
     private bool connected = false;
     public int port = 8338; //MH faceShiftOSC default port
     private OSCReceiver receiver;
     private Thread thread;
     UdpClient udpClient;
     IPEndPoint endPoint;
 
 
     
     private List<OSCMessage> processQueue = new List<OSCMessage>();
     
     public UnityOSCReceiver() {}
 
     public int getPort() {
         return port;
     }
             
     public void Start() {
         //endPoint = new IPEndPoint (IPAddress.Any, port);
     
         try {
             Debug.Log("connected");
             connected = true;
             receiver = new OSCReceiver(port);
             thread = new Thread(new ThreadStart(listen));
             thread.Start();
         } catch (Exception e) {
             Debug.Log("failed to connect to port "+port);
             Debug.Log(e.Message);
         }
     }
     
     /**
      * Call update every frame in order to dispatch all messages that have come
      * in on the listener thread
      */
     public void Update() {
         //processMessages has to be called on the main thread
         //so we used a shared proccessQueue full of OSC Messages
         lock(processQueue){
             foreach( OSCMessage message in processQueue){
             
                 BroadcastMessage("OSCMessageReceived", message, SendMessageOptions.DontRequireReceiver);
                 }
             processQueue.Clear();
         }
     }
     
     public void OnApplicationQuit(){
         disconnect();
     }
     
     public void disconnect() {
           if (receiver!=null){
                receiver.Close();
           }
           
            receiver = null;
         connected = false;
     }
 
     public bool isConnected() { return connected; }
 
     private void listen() {
 
         while(connected) {
             try {
 
                 OSCPacket packet = receiver.Receive();
 
                 if (packet!=null) {
                     lock(processQueue){
 
                         //Debug.Log( "adding  packets " + processQueue.Count );
                         if (packet.IsBundle()) {
                             ArrayList messages = packet.Values;
 
                         
                             for (int i=0; i<messages.Count; i++) {
                                 processQueue.Add( (OSCMessage)messages[i] );
                             }
                         } else{
                             processQueue.Add( (OSCMessage)packet );
                         }
                     }
                 } else Console.WriteLine("null packet");
             } catch (Exception e) { 
                 Debug.Log( e.Message );
                 Console.WriteLine(e.Message); 
             }
         }
     }
 }

Any clue how I can figure out which device the message was sent from so that I can apply it to the appropriate game object in a multiplayer environment.
