This addressing system is essential for routing traffic efficiently and ensuring that information reaches the intended destination.

The function of an IP address is critical in both local area networks (LANs) and wide-area networks (WANs), as it provides essential information about the device's location within the network. Additionally, there are two main types of IP addresses: IPv4 and IPv6, with IPv4 being the most widely used format, featuring a 32-bit structure to create over 4 billion addresses, while IPv6 expands this by using a 128-bit format to accommodate the growing number of devices connected to the internet.

A type of web URL refers to a system that allows users to access resources on the internet but is not an identifier like an IP address. A security protocol for networks refers to methods used for securing data and controlling access rather than
