What does the numerical label associated with internet devices and websites called?

The numerical label associated with internet devices and websites is known as an Internet Protocol Address, commonly referred to as an IP address. Every device connected to the internet must have a unique IP address, which serves two primary functions: identifying the device on the network and providing its location for data transmission.

IP addresses come in two versions, IPv4 and IPv6. IPv4 addresses consist of four sets of numbers ranging from 0 to 255, separated by periods (e.g., 192.168.1.1), while IPv6 addresses are longer and designed to accommodate the expansive growth of the internet as it allocates a significantly larger address space.

This numerical labeling is fundamental for routing internet traffic and enables devices to communicate with each other effectively. Without IP addresses, the internet as we know it would not be able to function, as there would be no standardized way to identify devices and website locations.

Other terms like Domain Name and Website Locator refer to user-friendly methods of identifying internet resources or specific websites but do not directly refer to the numerical labels essential for network communication. While Network Identifier is a broader term that could refer to various types of network labels, it does not specifically pinpoint the unique numerical aspect described in the question.
