Stateless address autoconfiguration (SLAAC)
On system startup, a node automatically creates a link-local address on each IPv6-enabled interface, even if globally routable addresses are manually configured or obtained through configuration protocols afterwards (see below). It does so independently and without any prior configuration by stateless address autoconfiguration (SLAAC), using a component of the Neighbor Discovery Protocol. Link-local addresses are in the prefix fe80::/64.
