The use of the Internet Protocol (IP) is essential for online communication and data exchange. This protocol defines the rules governing the interactions between a web browser requesting a page and the server that provides it. In the field of e-marketing, the IP is of paramount importance because it facilitates targeting, personalization, and audience measurement by enabling the transmission of key information. For example, the location of users on the internet is made possible by the browser communicating the device’s IP address upon connection.
