IPv6 addressing overview

5

The hexadecimal letters in IPv6 addresses are not case-sensitive

As shown in

Figure 9

, the IPv6 network prefix is composed of the left-most bits of the address. As

with an IPv4 address, you can specify the IPv6 prefix using the / format,
where the following applies.

The parameter is specified as 16-bit hexadecimal values separated by a colon.

The parameter is specified as a decimal value that indicates the left-most bits of
the IPv6 address.

The following is an example of an IPv6 prefix.

IPv6 address types

As with IPv4 addresses, you can assign multiple IPv6 addresses to a switch interface.

Table 22

presents the three major types of IPv6 addresses that you can assign to a switch interface.

A major difference between IPv4 and IPv6 addresses is that IPv6 addresses support scope, which
describes the topology in which the address may be used as a unique identifier for an interface or
set of interfaces.

Unicast and multicast addresses support scoping as follows:

Unicast addresses support two types of scope: global scope and local scope. In turn, local
scope supports site-local addresses and link-local addresses.

Table 22

describes global,

site-local, and link-local addresses and the topologies in which they are used.

Multicast addresses support a scope field, which

Table 22

describes.
