Getting ipaddress and location of every user visiting your website

Question

How do you get the ipaddress and location of every website vistor of your website through Asp.Net?

Thanks

Answer 1

To get the user's IP use:

Request.UserHostAddress

You can use this webservice to get their geographic location. http://iplocationtools.com/ip_location_api.php

Answer 2

 string VisitorIPAddress = Request.UserHostAddress.ToString();

and based on the ipaddress you can narrow down the location: find the geographical location of a host

Answer 3

Request.UserHostAddress won’t work if you're behind a proxy. Use this code:

public static String GetIPAddress()
{
    String ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (string.IsNullOrEmpty(ip))
        ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
    else
        ip = ip.Split(',')[0];

    return ip;
}

Note that HTTP_X_FORWARDED_FOR should be used BUT as it can return multiple IP addresses separated by a comma you need to use the Split function. See this page for more info.
