Link-Local
| IPv6 Address Type: | Link-Local |
| Prefix: | fe80::/10 |
| Local Routeable: | No |
| Global Routeable: | No |
| Global Unique: | No |
| Example: | FE80::21B:D4FF:FE0F:8CA2 |
| IPv4 Equivalent: | 169.254.0.0/16 Link-Local |
| Described in: | rfc4291 |
Explanation
These addresses are used on a single link or a non-routed common access network, such as an Ethernet LAN.
They do not need to be unique outside of that link.
Link-local addresses may appear as the source or destination of an IPv6 packet.
Routers must not forward IPv6 packets if the source or destination contains a link-local address.
IPv6 Link-Local Addresses
Link-Local Addresses are used by Nodes to communicate to other Nodes on the same Link. Link-Local addresses are not Routeable.
