A technician needs to verify if a new network interface can communicate within an IPv6 network. Which type of IP address should the technician look for to ensure that the interface has established automatic link-local addressing?
Link-local addresses are automatically configured on all IPv6-enabled interfaces and can be used to communicate with other hosts in the same network segment without the need for additional configuration. These addresses are in the fe80::/10 prefix range. A common misconception is to look for unique local addresses or site-local addresses; these are utilized in larger scopes or reserved for specific purposes and do not necessarily indicate successful interface operation in a local context. Global addresses are assigned for communication over the Internet, but their presence does not confirm the interface's ability to communicate on the local link.
