您无法在客户端获取IP地址-您必须引用服务器.客户端IP是不延伸通过路由器的本地地址(192.xxx.xxx.xxx或类似地址).同样，服务器看不到客户端的实际IP，而是看到由ISP分配的实际路由器的IP地址.

最简单的方法是询问服务器:

You can''t get the IP address at the client side - you have to refer to the server. The Client side IP is a local address (192.xxx.xxx.xxx or similar) which does not extend past the router. Equally, the Server cannot see the Client actual IP - it sees the IP address of the actual router, which is assigned by the ISP.

The easiest way to do it is to ask the server:

<br />Your IP address is <%= Request.ServerVariables["REMOTE_ADDR"] %><br />
