In a computer network, a link-local address is a network address that is valid only for communications within the network segment (link) or the broadcast domain that the host is connected to. Link-local addresses are usually not guaranteed to be unique beyond a single network segment.

Link-local addresses for IPv4 are defined in the address block 169.254.0.0/16, in CIDR notation.
In IPv6, they are assigned with the fe80::/10 prefix.

169.254.0.0/16 reserved for Link Local [RFC5735]
