Which of the following describes a link-local address?

A link-local address is specifically designed for communications on the local subnet and is not meant to be routed outside of that local network. These addresses are usually used for automatic address configuration, allowing devices on the same local network to communicate without the need for a central router or server.

Unlike globally routable addresses that can be reached from any other addressable point on the internet or within larger networks, link-local addresses are confined to their local network segment. Therefore, when devices communicate using link-local addresses, they are limited to interaction with other devices that are directly connected to the same physical or logical subnet.

The nature of link-local addresses also means they do not require any form of registration with a Domain Name System (DNS) or any specific organization for identification. This simplification allows for easier network setup, especially in ad-hoc networking environments.
