SLAAC (Stateless Address Auto-Configuration)

In a computer network, a link-local address is a network address that is valid only for communications within the network segment or the broadcast domain that the host is connected to.

Link-local addresses are most often assigned automatically through a process known as stateless address autoconfiguration or link-local address autoconfiguration.

Link-local addresses are not guaranteed to be unique beyond their network segment, therefore routers do not forward packets with link-local addresses.

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