IP2Location is database-driven solution to identify visitors' geographical location such as their location (country, region, city, latitude, longitude, ZIP code, time zone), connection speed, ISP and domain name using their
IP addresses. The technology is also known as IP
geolocation. The solution is platform independent and can be integrated by almost all database system such as mySQL, MS-SQL server or others. The solution also comes with API in several programming languages .NET, Java, C, C++, Visual Basic, PHP, ColdFusion, Perl, Ruby ad Python. IP2Location has been used by many other applications such as
Wikiscanner.
Accuracy and criticism
Critics note that geolocation software is inherently inaccurate and conflicts with the global nature of the Internet. A research done by University of Toronto reported that the accuracy of IP2Location is leading other commercial providers . The research was conducted based on datasets of 463 universities in United States and 1,000 broadband hosts. The accuracy is as high as 90% results within 50 km of error distance.
