Which of the following is true when describing an anycast address?

This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
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.
Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.
