Link-local address
Link-local address
IPv6 link-local addresses are automatically self-configured and allow IPv6 communications between hosts connected to the same link (routers do not forward link-local addresses). Because each IPv6 host on a local network assigns itself a link-local address, a router-based infrastructure is not required.
When the print server creates a link-local address, the link-local prefix FE80::/10 is combined with a 64-bit host address, derived from the print server’s MAC address, in accordance with a predefined algorithm.
For example, a print server with MAC address 00–0E-7F-E8–01–DD results in the following link-local address:
The use of link-local IPv6 addressing is beneficial for small, configuration free networks.
