外网地址与路由器的显示

[whaha]

上网方式很简单：无线路由器 + adsl拨号

路由器地址 192.168.1.1
登录后

在本机上
curl ip.gs
当前 IP：111.39.103.60

请问，为何路由器显示的wan地址为何是 100.65.60.15，为何和curl ip.gs显示的地址不一致？

traceroute sina.com.cn

試試
sudo tracepath sina.com.cn
參閱
http://manpages.ubuntu.com/manpages/tru ... .db.1.html
traceroute - print the route packets trace to network host

tracepath, tracepath6 - traces path to a network host discovering MTU along this path

原因很简单，因为我们在一个很大的局域网里。

运营商给你路由器WAN口上分配的100.65.60.15，对于整个互联网而言，此IP和192.168.x.x是没区别的，即：实际性质就是个 私网地址。
