System SP Tables-5
156 IPv6 Manual Address
This SP is the IPv6 manually set address referenced on the Ethernet or
wireless LAN (802.11) in the format:
"Manual Set Address" + "Prefix Length"
The IPv6 address consists of a total 128 bits configured in 8 blocks of 16 bits
each. These notations can be abbreviated. See "Note: IPV6 Addresses"
below this table.
158 IPv6 Gateway
This SP is the IPv6 gateway address referenced on the Ethernet or wireless
LAN (802.11). The IPv6 address consists of a total 128 bits configured in 8
blocks of 16 bits each. These notations can be abbreviated. See "Note: IPV6
Addresses " below this table.
Note: IPV6 Addresses
Ethernet and the Wireless LAN (802.11) reference the IPV6 "Link-Local address + 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: 0x0~0x80). 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
3. The IPV6 address is expressed in hexadecimal delmited by colons (:) with the
following characters:
0123456789abcdefABCDEF
4. A colon is inserted as a delimiter every 4th hexadecimal character.
fe80:0000:0000:0000:0207:40ff:0000:340e
5. The notations can be abbreviated by elminating 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
