In this short article I will explain how to get Country Name from IP Address in ASP.Net using C# and VB.Net.
The country name will be determined from IP Address using a Web Service.
The WebService
I am making use of the following free Web Service used for finding the geographical location of an IP Address.
Adding Reference of the Web Service in Visual Studio
1. Right click the project in Solution Explorer and choose Add Service Reference option from the context menu.

Accessing the Web Service and its Methods
Using the Web Reference Name given in step #4, you can access the Web Service and its methods.
HTML Markup
The HTML Markup consists of a TextBox, a Button and a Label control.
<asp:TextBox ID="txtIPAddress" runat="server" Text="" />
<asp:Button Text="Submit" runat="server" OnClick="GetCountry" />
<hr />
<asp:Label ID="lblCountry" runat="server" />
Fetching the location from the Web Service
Inside the Button click event handler, an object of GeoIPService is created and then IP Address is passed as parameter to the GetGeoIP method which returns the name of the Country to which the IP address belongs. It is then displayed using the Label control.
C#
protected void GetCountry(object sender, EventArgs e)
{
GeoService.GeoIPService service = new GeoService.GeoIPService();
GeoService.GeoIP output = service.GetGeoIP(txtIPAddress.Text.Trim());
lblCountry.Text = "Country: " + output.CountryName;
}
VB.Net
Protected Sub GetCountry(sender As Object, e As EventArgs)
Dim service As New GeoService.GeoIPService()
Dim output As GeoService.GeoIP = service.GetGeoIP(txtIPAddress.Text.Trim())
lblCountry.Text = "Country: " + output.CountryName
End Sub
