How can I get a client's local IP address, like 192.168.0.1?

Question

I have already tried all solutions in Stack Overflow question How to get a user's client IP address in ASP.NET?. It gives me the server's IP address, not the client's LAN IP address.

I need to get client's local IP address, and it must be seen as 192.168.2.1, but I always get the server's IP address instead of it.

Here is my code:

System.Web.HttpContext context = System.Web.HttpContext.Current;
string ipAddress = context.Request.ServerVariables["LOCAL_ADDR"];

There is a website doing this, http://net.ipcalf.com/.

How do I solve this issue?

no idea, but you can look at their soruce code for the answer, well assuming it's not a server side thing (which I seriously doubt) — LiranBo, Oct 26 '15 at 16:32

they're using an `RTCPeerConnection`. You can literally copy the HTML and script on that page into a text document and get the same results in Chrome and Firefox. They are doing it clientside — Jonesopolis, Oct 26 '15 at 16:39
You can't get the local client address any other place than at the client. It's not sent along in the request. — Guffa, Oct 26 '15 at 16:39
As far as I know, the only thing that worked for me was using ActiveX with Internet Explorer, but that makes the web site very restrictive ;) If that is no problem check: http://codingresource.blogspot.nl/2010/02/get-client-mac-address-ip-address-using.html?m=1 — Silvermind, Oct 26 '15 at 16:44

You want the remote address, not the local address

context.Request.ServerVariables["REMOTE_ADDR"]

Your code grabs the server IP address, not the client's. Try the following below:

This code was copied from Stack Overflow question How to get a user's client IP address in ASP.NET?.

protected string GetIPAddress()
{
    System.Web.HttpContext context = System.Web.HttpContext.Current;
    string ipAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

    if (!string.IsNullOrEmpty(ipAddress))
    {
        string[] addresses = ipAddress.Split(',');
        if (addresses.Length != 0)
        {
            return addresses[0];
        }
    }

    return context.Request.ServerVariables["REMOTE_ADDR"];
}
