The Internet Protocol (IP) is a fundamental communication protocol that governs the transmission of data across networks, forming the backbone of the internet. It provides a set of rules and conventions for devices to identify and communicate with each other on a network. Every device connected to the internet, whether a computer, smartphone, or server, is assigned a unique numerical label known as an IP address. IP addresses allow for the identification and location of devices in a network. There are two versions of IP in use today: IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6), with IPv6 introduced to address the limitations of IPv4 and accommodate the growing number of devices connected to the internet. IP works in conjunction with other protocols to facilitate the routing and delivery of data packets between devices, enabling seamless communication and data transfer across the global network. Understanding IP is fundamental to comprehending how devices interact and communicate in the vast landscape of the internet.
