如何使用变量作为套接字服务器IP地址

Question

因此，我想将一个变量作为套接字服务器IP地址...我有一些问题。我从server.bind（addr）错误消息中获取问题

import socket
import requests
import threading

def controller(conn, addr):
    connected = True
    while connected:
        msg_length = conn.recv(HEADER).decode(FORMAT)
        msg_length = int(msg_length)
        msg = conn.recv(msg_length).decode(FORMAT)
        if msg == DISCONNET:
            connected = False

        print(f'{msg}')

def start():
    print('Server: Server Started')
    server.listen()
    while True:
        conn, addr = server.accept()
        thread = threading.Thread(target = controller, args = (conn, adrr))
        thread.start()

host_name = socket.gethostname()    
prip = socket.gethostbyname(host_name)
puip = requests.get('https://api.ipify.org').text

HEADER = 128
PORT = 5050
SERVER = puip
ADDR = (SERVER, PORT)
FORMAT = 'utf-8'
DISCONNET = '!DISCONNECT'

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(ADDR)

start()

：

server.bind((SERVER, PORT))
OSError: [WinError 10049] The requested address is not valid in its context
