Unicast, multicast, and anycast are types of IPv6 addresses. The following are the IPv6 address types:

- Unicast address: These types of addresses are used to define a single destination interface. A packet sent to a unicast address is delivered to the specific interface.
- Multicast address: These types of addresses are used to define a group of hosts. When a packet is sent to a multicast address, it is delivered to all the hosts identified by that address. Multicast addresses begin with the prefix FF00::/8 and the second octet identifies the range over which the multicast address is propagated. Some special case IPv6 multicast addresses:
- FF01:0:0:0:0:0:0:1: Indicates all-nodes address for interface-local scope.
- FF02:0:0:0:0:0:0:2: Indicates all-routers address for link-local.
- Anycast address: These types of addresses are used to identify a set of devices. These addresses are also assigned to more than one interface belonging to different nodes. A packet sent to an anycast address is delivered to just one of the interfaces, based on which one is closest. For example, if an anycast address is assigned to a set of routers, one in India and another in the U.S., the users in the U.S. will be routed to U.S. routers and the users in India will be routed to a server located in India.

The broadcast option is incorrect because these types of addresses are not supported by IPv6. Broadcast functionality is provided by multicast addressing.

The dual-cast option is incorrect because this is not a valid Cisco address type.
