IPAddressExtensions - extending the System.Net.IPAddress class

UPDATED WIKI: Home

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;
 
IPAddress ipAddress = new System.Net.IPAddress(0x2414188f);  // Some IPv4 address in the USA.
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

Codeplex team didn't like my original logo and locked the project (thanks guys for notifying me!). Logo updated, project reopened. Appologies for any inconvience this might have caused.

NEW POST: Which compression method to use?

purekrome — Sat, 23 Feb 2008 13:18:08 GMT

I didn't know this, but the core .NET library contains support for GZip compression and decompression with the namespace System.IO.Compression . Nice! So I've gzip up the data file, made sure it's an embedded resource, then gzip decompressed it during the retrieval of the data.

RELEASED: Version 1.1.0.0 (Feb 24, 2008)

Sat, 23 Feb 2008 13:14:57 GMT

Binary dll has been reduced from around 5MB down to 800kb using gzip compression on the embedded data file. Joy :)

- Updated the assembly to version 1.1.0.0

- Added GZip decompression support. - GZipped the embedded data file.

CREATED FEATURE: Add compression to the embedded data item.

purekrome — Sat, 23 Feb 2008 11:44:44 GMT

Currently, the embedded data item is not compressed. This could be substantially compressed using a compression method like 7 Zip or Rar, etc..

CREATED RELEASE: Version 1.0.0.0 (Feb 23, 2008)

Sat, 23 Feb 2008 11:42:30 GMT

The initial release of the extension methods library.

- Initial release.

NEW POST: Which compression method to use?

purekrome — Sat, 23 Feb 2008 11:12:57 GMT

To improve the memory allocation, the embedded resource geospatial information should be compressed. Initially I was thinking of using the 7 Zip compression (LZMA) but when I downloaded the SDK there's a number of files and my initial thoughts where 'sigh... could be a bit too hard to figure out what is what, let alone what code i'm allowed to use legally, etc'.

Secondaly, I didn't want to have a dependency on a 3rd party DLL. This would mean that everytime someone uses this IP2Country dll, they would be required to have the 3rd party dll also.

So .. suggestions or thoughts?
