Which of the following describes the characteristics of a link-local IPv6 address?

A link-local IPv6 address has the characteristic of being only routable within the local network segment. This means that these addresses are intended for communication between nodes on the same local network and cannot be routed over the internet or between different networks. Link-local addresses are automatically configured on IPv6-enabled devices and typically have the prefix fe80::/10. Their non-routable nature is essential for ensuring local communications without requiring a globally unique address or any external configuration.

This characteristic allows devices to communicate with each other without the need for a router, making them particularly useful for purposes such as device discovery and neighbor discovery protocols within a small, local environment.
