The default is to configure addresses using MAC for IID, therefore by
default the las 24 bits would match the MAC. But this is only default and
not mandatory, I often use simple addresses such as fe80::1. So that's why
we go the longer route of joining a MLD group on the solicited node
multicast address, and when a packet is received we check if we belong to
the group.

This approach supports multiple addresses with different solicited node
multicast addresses.
