In mixed IPv4 and IPv6 address nodes, the format x:x:x:x:x:x:d.d.d.d is sometimes used where x is the hexadecimal values of the six high-order 16-bit address pieces, and d is the decimal value of the four low-order 8-bit pieces of the address (standard IPv4 representation). Table 6-4shows examples.

Cisco ANA NetworkVision displays compressed IPv6 addresses only.

IPv6 Address Prefix Text Representation

The text representation of IPv6 address prefixes is similar to the way IPv4 address prefixes are written in Classless Inter-Domain Routing (CIDR) notation. An IPv6 address prefix is represented by the notation:

ipv6-address/prefix-length

where:

ipv6-address is an IPv6 address in any of the notations listed previously.

prefix-length is a decimal value specifying how many of the furthest left contiguous bits of the address comprise the prefix.

The following are examples of IPv6 addresses with the 60-bit hexadecimal prefix,12AB00000000CD3:

12AB:0000:0000:CD30:0000:0000:0000:0000/60

12AB::CD30:0:0:0:0/60

12AB:0:0:CD30::/60

When writing both node address and a prefix of that node address (for example, the node's subnet prefix), the two can be combined. For example, the node address, 12AB:0:0:CD30:123:4567:89AB:CDEF, and its subnet number, 12AB:0:0:CD30::/60, can be abbreviated as:

12AB:0:0:CD30:123:4567:89AB:CDEF/60

Cisco ANA supports all the textual presentations of address prefixes. However, Cisco ANA

NetworkVision displays both the IP address and the subnet prefix, for example:

12AB::CD30:123:4567:89AB:CDEF, 12AB:0:0:CD30::/60
