公网的IP、外网IP分别是什么意思?
Release date:2022.11.22
source: internet

公网的IP、外网IP是一个意思,都是指你在互联网上的IP地址,但是这个地址可能不是你电脑的地址,而是你所在的局域网地址,就象你的宿舍在你大学里,但是从外面看你的宿舍地址就是你大学的地址,只有进了你学校才能进一步找到你宿舍地址一样。这里,学校地址就类似外网IP,宿舍地址就是内网IP。你到www.ip138.com上就可以看到你自己的外网IP。
本地连接状态里显示的是内网IP,宽带连接状态显示的是外网IP。外网IP是每次上网都不一样的(如果你是ADSL拨号宽带的话)。远程桌面要使用的IP是外网IP,但是只能连到你所在的局域网网关(相当于学校大门),能否到你自己电脑还不一定,要看网关上有没有做映射。
如果你是ADSL宽带且没有用路由器之类的设备,就别考虑那么多了,你只有一个外网IP,没有内网IP,因为不存在局域网,你的宿舍门就是学校大门,呵呵
