之前写过用Docker实现DDNS更新,但是对于ARM的N1来说增加的负载负担还是让人有些苦恼的(虽然增加的并不多,但是还是会想要优化得更好一些!)既然想到了这里,那就用更便捷的方式来实现吧!
由于我的N1在Armbian上安装了宝塔面板,并架设了NextCloud(性能低下)所以还是装了Cloudreve,利用IPv6实现外网的便捷访问。Docker使用仅仅是为了DDNS还是很浪费资源的。所以就使用宝塔的计划任务来实现吧!

配置好了之后保存,可以尝试执行一次看是否已经生效,如果正常就OK啦!是不是很简单?
IPV4网络如何访问IPV6的资源呢,请赐教
之前发现IPV4无法访问IPV6,只好关闭了IPV6
如果你当前的网络没有ipv6网络,可以使用He.net的ipv6隧道试试!
