[2.5.6](https://www.rfc-editor.org/rfc/rfc4291.html#section-2.5.6).  Link-Local IPv6 Unicast Addresses

Link-Local addresses are for use on a single link.  Link-Local
addresses have the following format:

    |   10     |
    |  bits    |         54 bits         |          64 bits           |
    +----------+-------------------------+----------------------------+
    |1111111010|           0             |       interface ID         |
    +----------+-------------------------+----------------------------+

Link-Local addresses are designed to be used for addressing on a
single link for purposes such as automatic address configuration,
neighbor discovery, or when no routers are present.

Routers must not forward any packets with Link-Local source or
destination addresses to other links.

Link-Local addresses are designed to be used for addressing on a single link for purposes such as automatic address configuration, neighbor discovery, or when no routers are present. Routers must not forward any packets with Link-Local source or destination addresses to other links.

A link-local address is only used on a single link. Traffic on a link-local network is confined to that network and cannot be routed to a different network. All IPv6 interfaces use the same link-local network, so addresses on one link-local network are the same on a different link-local address.
