Note : IPV6 Addresses
Ethernet and the Wireless LAN (802.11) reference the IPV6 "Link-Local a Prefix
Length". The IPV6 address consists of 128 bits divided into 8 blocks of 16 bits:
aaaa:bbbb:cccc:dddd:eeee:ffff:gggg:hhhh:
The prefix length is inserted at the 17th byte (Prefix Range: 0x0to0x80). The initial setting is
0x40(64).
For example, the data:
2001123456789012abcdef012345678940h
is expressed:
2001:1234:5678:9012:abcd:ef01:2345:6789: prefixlen 64
However, the actual IPV6 address display is abbreviated according to the following rules.
Rules for Abbreviating IPV6 Addresses
1. The IPV6 address is expressed in hexadecimal delimited by colons (:) with the
following characters:
0123456789abcdefABCDEF
2. A colon is inserted as a delimiter every 4th hexadecimal character.
fe80:0000:0000:0000:0207:40ff:0000:340e
3. The notations can be abbreviated by eliminating zeros where the MSB and digits
following the MSB are zero. The example in "2" above, then, becomes:
fe80:0:0:0207:40ff:0:340e
4. Sections where only zeros exist can be abbreviated with double colons (::). This
abbreviation can be done also where succeeding sections contain only zeros (but this
can be done only at one point in the address). The example in "2" and "3" above then
becomes: fe80 :: 207:40ff:0:340e (only the first null sets zero digits are abbreviated as
"::")
-or-
fe80:0:0:0:207:40ff :: 340e (only the last null set before "340e" is abbreviated as "::")
