IPv6 Address Format
The basic format of an IPv6 address is X : X : X : X : X : X : X : X, where X is a 4 hex
integers (16 bits). Each digit contains 4 bits of information, each integer contains 4 hex
digits and each address contains 8 integers, so it is total for 128 bits. Some legal IPv6
addresses are as follows:
2001:ABCD:1234:5678:AAAA:BBBB:1200:2100
800 : 0 : 0 :0 : 0 : 0 : 0 : 1
1080 : 0 : 0 : 0 : 8 : 800 : 200C : 417A
These integers are hex integers, where A to F denote 10 to 15 respectively. Each
integer in the address must be denoted and the starting 0 needs not be denoted.
Some IPv6 address may contain a series of 0s (such as the examples 2 and 3). Once
this condition occurs, the “: :” is allowed to denote this series of 0s. Namely, the
address 800:0:0:0:0:0:0:1 can be denoted as: 800 :: 1
These two colons denote that this address can be extended to the complete 128-bit
address. In this way, the 16-bit group can be replaced with two colons only when they
are all 0s and the two colons can only present for one time.
In the mixture environment of IPv4 and IPv6, there is a mixture denotation method.The
lowest 32 bits in an IPv6 address can be used to denote an IPv4 address. The
address can be expressed in a mixture mode, i.e., X: X : X : X : X : X : d . d . d . d.
Where, the X denotes a 16-bit integer, while d denotes an 8-bit decimal integer. For
instance, the address 0 : 0 : 0 : 0 : 0 : 0 : 192 .168 . 20 : 1 is a legal IPv6 address. After
the abbreviated expression method is used, this address can be denoted as follows: : :
192 .168 . 20 . 1
For the IPv6 address is divided into two parts such as the subnet prefix and the
interface identifier, it can be denoted as an address with additional numeric value by
the method like the CIDR address. Where, this numeric value indicates how many bits
represent the network part (the network prefix). Namely the IPv6 node address
indicates the length of the prefix, and the length is differentiated from the IPv6 address
by the slash. For instance: 12AB::CD30:0:0:0:0/60,The length of the prefix used for
routing in this address is 60 bits.
Type of IPv6 Address
In RFC2373, there are the following three defined types of IPv6 addresses:
