GODADDY DDNS 自动更新脚本

把下面脚本放到，路径自己决定
/data/services/godaddy/ddns.sh
然后 crontab -e 添加，频率自己修改
*/5 * * * * /data/services/godaddy/ddns.sh >> /data/services/godaddy/ddns.log

顺便找了几个获取公网IP的接口
http://ip-api.com/json/?lang=zh-CN

有频率限制，不能短时间内重复调用，应该是因为可以查任意IP归属地，所以限制了
http://ip.taobao.com/service/getIpInfo.php?ip=myip
这个也可以任意查任意IP归属地
http://ip-api.com/json/113.97.18.125?lang=zh-CN
