在asp.net或javascript中如何获取Lan IP而不是公共IP

Question

My local IP address in 192.168.0.11. How can i get this using ASP.NET or Javascript.

Currently i am using the below which returns my Public IP Address

Dim ip As String = HttpContext.Current.Request.ServerVariables("REMOTE_ADDR")

i googled many times but every method i got returns my Public IP.

Is it possible to get this info using asp.net or javascript.

Answer 1

You can't. Client-side JavaScript doesn't deal with IP's at all, and server-side languages really have no access to local IP's for the simple reason that this data is not being sent to the server.

If you really want to obtain the local IP, you're going to have to get the user to install some kind of software on their PC.
