What is the IPv6 prefix that is used for link-local addresses?
Answers Explanation & Hints:
The IPv6 prefix that is used for link-local addresses is FE80::/10.
Link-local addresses are used for communication between devices on the same link or network segment. The FE80::/10 prefix is reserved for link-local addresses, which means that any IPv6 address that starts with FE80 will be a link-local address.
Link-local addresses are automatically assigned to interfaces when IPv6 is enabled on the interface, and they do not require any manual configuration. They are used for tasks such as neighbor discovery, address autoconfiguration, and router discovery, and they are not routable outside of the local link or network segment.
