Three categories of IPv6 addresses exist:
- Unicast – represents a single interface. Packets addressed to a unicast address are delivered to a single interface.
- Anycast – identifies one or more interfaces. For example, servers that support the same function can use the same unicast IP address. Packets sent to that IP address are forwarded to the nearest server. Anycast addresses are used for load-balancing. Known as “one-to-nearest” address.
- Multicast – represent a dynamic group of hosts. Packets sent to this address are delivered to many interfaces. Multicast addresses in IPv6 have a similar purpose as their counterparts in IPv4.
IPv6 doesn’t use the broadcast method. It has been replaced with anycast and multicast addresses.
