推荐答案

获取机器互联网IP地址的唯一方法是与路由器另一端的人交谈. (或其他任何方式)将您连接到互联网.原因是在它的您"一侧，您的IP地址是本地地址:例如192.168.0.2.仅另一端的设备获得IP地址，该IP地址不特定于您的PC-特定于您的Internet连接而不是您的PC，例如，如果有两个PC连接到同一路由器，则可以共享该IP地址.路由器将重定向消息，并根据需要使用正确的内部/外部地址.

因此，您需要与whatsmyIP或类似的外部服务进行对话，以了解值是什么！

The only way to get the internet IP address of a machine is to talk to something on the otherside of the router (or whatever) that connects you to the internet. The reason being that on "your" side of it, your IP address is a local one: 192.168.0.2 for example. Only the equipment one the other side gets the IP address, which is not specific to your PC - it is specific to your internet connection not your PC, and may be shared if there are two PC connected to the same router, for example. The router redirects messages, and uses the correct internal / external address as appropriate.

So you need to talk to whatsmyIP or a similar external service to find out what the value is!
