Every computer connected to the Internet is assigned a unique number known as an Internet protocol (IP) address. Since these numbers are usually assigned in country-based blocks, an IP address can often be used to identify the country from which a computer is connecting to the Internet. TELES collects the IP address of website visitors in order to provide website owners with the relevant content. This method is known as IP geolocation. As to do so, this website includes GeoLite data created by MaxMind.
