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.
