10.6 Summary
The use of scope, especially to differentiate between the local network and
the global IPv6 Internet, is an important reason why multicast can be so
much more useful in IPv6 networks than it has been in IPv4 networks.
An integral part of IPv6 protocols, we will see how multicast performs
important functions in ICMPv6 in Chapter 12, as well as related protocols
such as Neighbor Discovery (Chapter 13), Mobile IPv6 (Chapter 17), and
elsewhere.
Though related to multicast, IPv6 anycast addressing differs in important
ways. As will become clear in the next chapter, anycast has the potential
to improve IPv6 network ...
