Computer Networking Which of the following is true when describing a multicast address? Identifies multiple interfaces and is only delivered to one address. This address can also be called one-to-one-of-many. Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address. 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.
