家用服务器自动更新腾讯云域名的ipv6地址

家用服务器自动更新腾讯云域名的ipv6地址，解决ipv6地址变化导致域名无法访问问题。
注意token这里是id+密钥
腾讯云token获取地址：https://console.dnspod.cn/account/token/token

import requests
import socket

# 配置
TOKEN = '12345,xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'  # 替换为你自己的Token
DOMAIN = 'fengche.site'
SUBDOMAIN = '@'  # 根域名用@，www用www

        print("获取IPv6失败:", e)
        ip = None
