 Multicast address: An identifier for a set of interfaces (typically belonging to different nodes), similar to an IPv4 multicast address. A packet sent to a multicast address is delivered to all interfaces identified by that address. There are no broadcast addresses in IPv6. Their function is superseded by multicast addresses.  Anycast address: An identifier for a set of interfaces (typically belonging to different nodes). A packet sent to an anycast address is delivered to one of the interfaces identified by that address (the nearest one, according to the routing protocols' measure of distance). The type of an IPv6 address is designated by the first several bits called format prefix. The following table lists the mappings between address types and format prefixes.

The two most common types are introduced below:  Global unicast address A Global unicast address is an IPv6 unicast address that is globally unique and is routable on the global Internet. Global unicast addresses are defined by a global routing prefix, a subnet ID, and an interface ID. Except for addresses that start with binary 000, all global unicast addresses have a 64-bit interface ID.

Table 4-1 Mappings between address types and format prefixes

IPv6 unicast address can be classified into several types, including global unicast address,

link-local address, and site-local address. The two most common types are introduced below:



Global unicast address

A Global unicast address is an IPv6 unicast address that is globally unique and is routable

on the global Internet.

Global unicast addresses are defined by a global routing prefix, a subnet ID, and an

interface ID. Except for addresses that start with binary 000, all global unicast addresses

have a 64-bit interface ID. The IPv6 global unicast address allocation uses the range of

addresses that start with binary value 001 (2000::/3). The figure below shows the structure

of a global unicast address.
