There are a lot of services out there. By using them, we can get the website visitor's geographical information such as country, region, city, latitude, longitude, ZIP code, time zone, and so on. It is possible just by using the IP address of the website visitor's machine.

In this article, I am using a service provided by http://iplocationtools.com/. This service is free and, based on the IP, returns geographical data in 3 formats.

  1. XML
  2. JSON
  3. CSV

This is the aspx code.

Here is the code behind it.

using System;
using System.Xml.Linq;
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    protected void btnGetLoc_Click(object sender, EventArgs e)
    {
        string url = string.Empty;
        if (txtIP.Text.Trim() != string.Empty)
        {
            url = string.Format("http://iplocationtools.com/ip_query2.php?ip={0}", txtIP.Text.Trim());
            XDocument xDoc = XDocument.Load(url);

            if (xDoc == null || xDoc.Root == null)
            {
                throw new ApplicationException("Data is not Valid");
            }
            Xml1.TransformSource = "IP.xslt";
            Xml1.DocumentContent = xDoc.ToString();
        }
    }
}

Here, I also observe that an XML control (<asp: Xml ID="Xml1") has been added to the page.

Our XSLT will look similar to the following.

<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

When you run the application and enter an IP address, you will get data something like this.

IP address

Now, if you wish to get the geographical information of your website visitors, you can simply get the IP address of a visitor from the browser, pass that IP address to this service, and get the desired data you want.
