IPv6 Addressing
IPv6 addressing overview
Table 93 displays the individual devices and the IPv6 Addressing features they support.
This chapter includes overview information about the following topics:
• IPv6 addressing.
• The IPv6 stateless auto-configuration feature, which enables a host on a local link to
automatically configure its interfaces with new and globally unique IPv6 addresses associated
with its location.
A limitation of IPv4 is its 32-bit addressing format, which is unable to satisfy potential increases in
the number of users, geographical needs, and emerging applications. To address this limitation,
IPv6 introduces a new 128-bit addressing format.
An IPv6 address is composed of 8 fields of 16-bit hexadecimal values separated by colons (:).
Figure 34 shows the IPv6 address format.
