Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.
Packets addressed to a unicast address are delivered to a single interface.

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
