IPv6 Multicast Addresses

Must like the reserved Class D address space in IPv4, IPv6 dedicates some of its address space to multicast traffic, albeit a much larger portion. If you recall, a multicast transmission is one in which a single transmission is received by many systems, or a one-to-many technique. In IPv6, multicasts use the prefix FF00::/8. Common examples of multicast addresses used in IPv6 include the destination address FF02::1, which is used to send a multicast to all hosts on a given subnet. Similarly, the multicast address FF02::2 is used to communicate with all routers on a subnet. Later in this series you’ll learn more about how some routing protocols use multicasts to facilitate inter-router communication.
