·Unicast address Identifies a single node or interface.Traffic destined for a unicast address is forwarded to a single interface. ·Multicast address Identifies a group of nodes or interfaces.Traffic destined for a multicast address is forwarded to all the nodes in the group. ·Anycast address Identifies a group of nodes or interfaces.Traffic destined to an anycast address is forwarded to the nearest node in the group.An anycast address is essentially a unicast address assigned to multiple devices with a host ID =0000:0000:0000:0000.(Anycast addresses are not widely used today.) With IPv6,broadcast addresses are no longer used
◼ With IPv6, broadcast addresses are no longer used
