Understanding IPv6

Use the Search field to locate the Cisco IOS software documentation. For example, if you want
information about static routes, you can enter Implementing Static Routes for IPv6 in the search field
to get this document about static routes:

IPv6 Addresses

The switch supports only IPv6 unicast addresses. It does not support site-local unicast addresses, anycast
addresses, or multicast addresses.

The IPv6 128-bit addresses are represented as a series of eight 16-bit hexadecimal fields separated by
colons in the format: n:n:n:n:n:n:n:n. This is an example of an IPv6 address:

2031:0000:130F:0000:0000:09C0:080F:130B

For easier implementation, leading zeros in each field are optional. This is the same address without
leading zeros:

2031:0:130F:0:0:9C0:80F:130B

You can also use two colons (::) to represent successive hexadecimal fields of zeros, but you can use this
short version only once in each address:

2031:0:130F::09C0:080F:130B

For more information about IPv6 address formats, address types, and the IPv6 packet header, see the
“Implementing IPv6 Addressing and Basic Connectivity” chapter of Cisco IOS IPv6 Configuration
Library
on Cisco.com.

In the “Information About Implementing Basic Connectivity for IPv6” chapter, these sections apply to
the switch:
