The IPv6 Internet is divided into addressing zones and IPv6 addresses can be categorized by type and scope.
IPv6 addressing is represented in RFC 4291.
Unicast
Unicast addresses provide one-to-one communication.
Multicast
Multicast addresses are similar in operation to IPv4 and provide one-to-many communication.
Anycast
An Anycast address is a Unicast address used for several devices to allow them to communicate with the device closest to the source; one-to-nearest communication.
Broadcast
In IPv6, broadcast addresses have been superseded by multicast addresses per RFC 4291.
For more information about address types and scopes, see IPv6 Address Types.
node-local
link-local
global
The switch does not support site-local addresses and, according to RFC 4193, site-local addresses will be replaced by unique-local addresses.
For more information about address types and scopes, see IPv6 address formats.
The IPv6 Internet is divided into zones.
Each node is a separate zone of the node-local scope.
Each link is a separate zone of the link-local scope.
The entire Internet is a single zone of global scope.
Zones of the same scope do not overlap.
