每一次更换IP解锁配置就失效
ip变更时，只需要更新dnsmasq的目标解析IP就可以了，例如批量替换1.2.3.4到5.6.7.8：
sed -i "s/1.2.3.4/5.6.7.8/g" /etc/dnsmasq.d/custom_netflix.conf
替换完重启使其生效 systemctl restart dnsmasq

名字给你说错了，是
autoupdateip.sh
bash autoupdateip.sh ddns网址 tail: cannot open '/tmp/autochangeip.log' for reading: No such file or directory

最近正好换ip，试了下自动脚本，脚本运行了没有报错，但是查看文件并没有修改成功。最终还是靠这个手动命令改成功了，然后Restart后生效叻！
可以执行
bash -x autoupdateip.sh，看一下脚本运行过程，方便排错
