Broadcast Addressing. IPv6 does not implement traditional IP broadcast, and therefore does not define broadcast addresses. In IPv6, the same result can be achieved by sending a packet to the link-local all nodes multicast group which is analogous to IPv4 multicast.
IPv6 has three types of addresses, which can be categorized by type and scope:
- Unicast addresses. A packet is delivered to one interface.
- Multicast addresses. A packet is delivered to multiple interfaces.
- Anycast addresses. A packet is delivered to the nearest of multiple interfaces (in terms of routing distance).
