• Divide the 128 bits of the IPv6 address into eight fields of 16 bits each.
Express the value of each field as a 4-digit hexadecimal number, and
separate each field with a colon (:).
Example 1: fe80:0000:0000:0000:0200:87ff:feb2:0c24
• You can omit the leading 0 of each field. If the value of a field is 0000,
specify 0 for that field.
The address in example 1 can be specified as follows:
Example 2: fe80:0:0:0:200:87ff:feb2:c24
• If the values of two or more consecutive fields is 0000, the fields can be
abbreviated as ::.
The address in the example 1 can be specified as follows:
Example 3: fe80::200:87ff:feb2:c24
• The abbreviation :: can be used only once per address.
• If the fields whose value is 0000 are not consecutive, specify 0 for each
field, without using ::.
• You can use numbers 0 to 9, lowercase letters a to f, and uppercase
letters A to F when specifying hexadecimal numbers.
• The address must start with either a hexadecimal number or ::.
IPv6 addresses are displayed in the format described from (1) to (4). As a
result, the displayed address might differ from the address you specified.
(1) The 128 bits of the IPv6 address are divided into eight fields of 16 bits
each. The value of each field is expressed as a 4-digit hexadecimal number,
and the fields are separated by colons (:). Hexadecimal numbers consist of
the numbers 0 to 9 and lowercase letters a to f.
(2) The leading 0 of each field in (1) is omitted. A field whose value is 0000 is
expressed as 0.
(3) Two or more consecutive fields of 0000 are replaced with ::.
(4) If more than one set of consecutive fields can be replaced by ::, the set
containing the largest number of such fields is replaced. If each set contains
the same number of fields, the first set is replaced.
Format check
The items to be checked when specifying IPv4 or IPv6 addresses are as
follows:
(1) Addresses must be specified in accordance with the rules listed above.
(2) For the default gateway configuration, an address that is accessible
from the address of the module must be specified.
(3) For DNS configuration, if the default gateway is not configured, an
address that is accessible from the address of the management module
must be specified.
(4) When specifying IPv6 addresses, the following addresses cannot be
used:
