The IPSearchLight ASP.Net WebControl (C# & VB.Net) tracks website visitors' geographic location including their country, region, city, postal code, latitude and longitude. Since it only uses their IP address, the technology is unintrusive and undetectable. The use of IPSearchLight's GeoLocator allows you to create localized content, target advertizing, enhance statistical analysis, improve security, increase fraud prevention, and much more.
