Use this function:

 public string GetLanIP()
    {
        IPHostEntry host;
        string localIP = "?";
        host = Dns.GetHostEntry(Dns.GetHostName());
        foreach (IPAddress ip in host.AddressList)
        {
            if (ip.AddressFamily == AddressFamily.InterNetwork)
            {
                localIP = ip.ToString();
            }
        }
        return localIP;

    }

You can't.

Browsers don't send their local IPs in HTTP headers, so there is no way for you to get it. You only get the router's external (internet) IP.

I assume you're using asp.net and in that case you could use Request.UserHostAddress to retrieve the IP address of a client.

Method 1:

You can get that by using below mentioned link.

List the IP Address of all computers connected to a single LAN

Method 2:

You can try below one also.

public string GetUserIP()
    {
        string ipList = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

        if (!string.IsNullOrEmpty(ipList))
        {
            return ipList.Split(',')[0];
        }

        return Request.ServerVariables["REMOTE_ADDR"];
    }

Method 3:

System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName()).AddressList.GetValue(0).ToString();

I hope this will help to you.
