Project Description
This is a .NET 3.5 library that retrieves the country information for an Internet Protocol version 4 (IPv4) Address, by extending the System.Net.IPAddress class.

The most common use for this library would be determining the destination of a user connecting to your website or application. You could then localise the webpages or data based on there IPv4 address geospatial location.

Information provided

  • Country name (eg. Australia)
  • Country ISO 3166 2-Code (eg. AU)
  • Country ISO 3166 3-Code (eg. AUS)
  • Registry. (eg. APNIC)
  • Date the IP Address (range) was added to the data source (if known).

Sample C# code

using System.Net;
using WorldDomination.Net;

string userHostIpAddress = "203.1.2.3";
IPAddress ipAddress;
if (IPAddress.TryParse(userHostIpAddress, out ipAddress))
{
    string country = ipAddress.Country(); // return value: UNITED STATES
    string iso3166TwoLetterCode = ipAddress.Iso3166TwoLetterCode(); // return value: US
}



The project was developed with the following :-
  • .NET 3.5 framework :: automatic properties, extension methods and anonymous types,
  • LINQ to OBJECTS to retrieve the data
  • Free geospatial data provided kindly by Webnet77 under the terms of the General Public License.
