[Host] May I ask how Netly can change the UDP receiver in real-time in Unity？I use server.Open(<host>) changing IP does not work.

For example, if the server is sending messages every second to 1.1.1.1, I would like to change it to 1.2.2.2 at this time

server.Open
can't change host when connection is opened, because connection is already opened. use server.Close to netly stop bind old ip and port, after use server.OnClose to receive close connection notice, and on server.OnClose open connection again using new Host instance and all will running perfectly.

using Netly;
using Netly.Core;
using System;
using UnityEngine;

public class UdpServerExample : MonoBehaviour
{
    // unity side
    public string ip = "127.0.0.1";
    public int port = 12000;
    private KeyCode reconnectKeyCode = KeyCode.Enter;

    private Host host = null;
    private bool useNewHost = false;
    private UdpServer server = new UdpServer(false);

    private void Awake()
    {
        server.OnOpen(() =>
        {
            print($"server: connection opened: {server.Host}");
            // more stuff here...
        });

        server.OnData((client, buffer) =>
        {
            print($"server: receive data from ({client.Host}): {NE.GetString(buffer)}");
            // more stuff here...
        });

        server.OnClose(() =>
        {
            if (useNewHost)
            {
                print($"server reconnecting: old ({server.Host}); new ({host});");

                // reconnecting with new Host;
                useNewHost = false; // set false because it is used
                server.Open(host);

                // return for not doing wrong on default behaviour
                return;
            }

            print($"server: connection closed: {server.Host}");
            // more stuff here...
        });
    }

    private void Start()
    {
        host = new Host(ip, port);
        server.Open(host);
    }

    private void Update()
    {
        if (Input.GetKeyDown(reconnectKeyCode))
        {
            ChangeHost(new Host(ip, port));
        }
    }

    private void ChangeHost(Host newHost)
    {
        host = newHost;
        useNewHost = true;
        // it will close connection, on OnClose event it will reconnect with new host.
        server.Close();
    }
}

It's working?
