什么是Dynamic DNS

Dynamic DNS是一个DNS服务。当您的设备IP地址被互联网服务提供商动态变更时,它提供选项来自动变更一个或多个DNS记录的IP地址。 此服务在技术术语上也被称作DDNS或是Dyn DNS 如果您没有一个静态IP,那么每次您重新连接到互联网是IP都会改变。为了避免每次IP变化时手动更新您的记录,您可以为您的域搭建Dynamic DNS。

此类型服务是最普遍使用在移动设备上。(如安保摄像头,本地服务器等等)。动态DNS帮助人们不丢失对其设备的访问,无论其家庭IP是否可能发生更改。 为什么会有这种情况发生?ISPs通常为客户在确定的一段时间内分配一个动态的IP地址。当那段时间结束后,他们会重新分配一个新的。
