I have a web application that has a login. Now what I want is to get the IP address of that end user upon login. I've tried researching but based on what I understood, it gets the ip of my machine not the person that logins. This app is already deployed on a server. And if I do what they said, I will be getting the server's ip address. But I want the IP address of the end user that logs in. 

This is a sample of what I've seen.

```
private string GetIP()
{
    string strHostName = "";
    strHostName = System.Net.Dns.GetHostName();

    IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName);

    string ipaddress =convert.tostring(ipEntry.AddressList[2]);

    return ipaddress.tostring();

}

```

I'm not sure if I understood this correctly but I think this will get local ip address, not the ip address of the end user that is logging in. Please do correct me if I'm wrong. Any ideas? Thanks!
