Answer:
Link-local address
Explanation:
IP addresses that have "FE80" as the hexadecimal representation of their first 10 bits are IPV6 reserved addresses for link-local unicast addressing. These addresses are automatically configured (though may be manually configured too) on any interface and should not be routed. They are used for addressing on a single link with the main aim, among others, of automatic configuration and routing protocol advertisement. Devices attached to this link can be accessed or reached using the link-local addresses as they don't need a global address to communicate.
However, routers will not forward datagram or packets using link-local addresses. In other words, routers are not allowed to connect to the internet using the unicast link-local addresses.
