IPSearchLight (www.ipsearchlight.com) for ASP.NET gives you real-time feedback on the geographic location of website visitors by their IP address alone. The technology is completely unintrusive, yet can often track a person's location to a few miles radius on the planet.
Some potential uses:
- Localization of website language, content and currency.
- Targeted advertising.
- Preventing credit card fraud.
- Geographically profiling email recipients.
- Geographic profiling of e-commerce purchasing behavior.
IPSearchLight for ASP.NET benefits from 1 click integration with the Microsoft Visual Studio 2002/2003 toolbox. It is packaged as a web control and can be implemented with minimal code overhead.
Quickstart:
IPSearchLight is most easily installed by using the installer executable, which can be downloaded from www.ipsearchlight.com.

Choose the directory you wish to install to (the given directory is recommended) and the installer will begin to extract and copy the database and other files:

The Installer will then automatically install IPSearchLight to the Microsoft Visual Studio Toolbox.
To use IPSearchLight, drag the WebControl onto your ASPX page from the Toolbox.
The component's properties are visible in the properties dialog window. The component will automatically detect each website visitor's location and IP address. Properties including longitude, latitude, state, country and postal (zip) code are then programatically accessible (See the examples section for more information).

You will need to acquire a Trial or Full License Key from www.ipsearchlight.com (it will run only 3 times without it).The license file should be placed in your website as follows: "{root}/bin/IPSearchLight . GeoLocator . lic " .
Your Trial License will expire after 30 days.
If you find that the data responses you're getting out of the IPSearchLight component are not sufficiently accurate, there are several upgrade options available.
