GeoIP locates a computer terminal’s geographic location by identifying that terminal’s IP address.
A form of geolocation, GeoIP refers to the method of locating a computer terminal’s geographic location by identifying that terminal’s IP address. Though GeoIP can pinpoint a terminal’s location to a city, it requires the use of a GeoIP database as well as an understanding of APIs to implement correctly.
Furthermore, GeoIP is not as accurate as other methods of geolocation, such as GPS and mobile technology, though no geolocation system delivers perfect accuracy. It is also possible for experienced users to camouflage alter their apparent location from GeoIP systems.
The most prevalent application of GeoIP involves geo-targeting, or determining a computer’s location in order to tailor content specifically for that location. Geo-targeting is most often used for targeted advertising, statistical research, spam prevention, and for restricting access based on location.
