Which of the following is true when describing a link-local address?

• Packets addressed to a unicast address are delivered to a single interface.
• These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
• These are like private addresses in IPv4 in that they are not meant to be routed.
• These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
