Python 套接字 IPV6（信使）

Question

所以我想用 python 做一个信使应用程序，我创建了一个客户端脚本和一个服务器脚本，服务器可以处理多个连接并且它现在工作得很好。我现在的问题是我的 ISP 没有给我公共 ipv4。所以我需要使用 ipv6 作为服务器，有什么方法可以做到这一点吗？ 那是我的服务器脚本

        print("%s:%s has connected." % client_address)
        client.send(bytes("Enter please a Username to join this Chatroom", "utf8"))
        addresses[client] = client_address
        Thread(target=handle_client, args=(client,)).start()

            del clients[client]

            break

    """Broadcasts a message to all the clients."""

    for sock in clients:
        sock.send(bytes(prefix, "utf8")+msg)
        print(bytes(prefix,"utf8")+msg)

    ACCEPT_THREAD = Thread(target=accept_incoming_connections)
    ACCEPT_THREAD.start()
    ACCEPT_THREAD.join()
    SERVER.close()

将套接字更改为 client_socket = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)。
