It never assigns an address itself, under any circumstances. That distinction shapes every command in this setup, and...

SLAAC and DHCPv6

Recall that the router sends a Router Advertisement (RA) message, and the settings within that RA message decide whether a client can obtain its IPv6 address information automatically using SLAAC, DHCPv6, or a combination of both. This guide covers both methods, the three possible RA flag combinations, and how to configure and verify each on...
