D–6Understanding IP addresses
Hitachi Storage Navigator Modular 2 User’s Guide
For example, for the MAC address of 00-60-08-52-F9-D8:
• The hexadecimal digits 0xFF-FE are inserted between 0x08 (the third
byte) and 0x52 (the fourth byte) of the MAC address, forming the 64-
bit address of 00-60-08-FF-FE-52-F9-D8.
• The Universal/Local bit, the second low-order bit of 0x00 (the first
byte) of the MAC address, is complemented. The second low-order bit
of 0x00 is 0 which, when complemented, becomes 1. The result is that
for the first byte, 0x00 becomes 0x02.
As a result, the IPv6 interface identifier that corresponds to the Ethernet
MAC address of 00-60-08-52-F9-D8 is 02-60-08-FF-FE-52-F9-D8.
The link-local address of a node is the combination of the prefix FE80::/64
and the 64-bit interface identifier expressed in colon-hexadecimal notation.
As a result, the link-local address of this example node, with the prefix
FE80::/64 and the interface identifier 02-60-08-FF-FE-52-F9-D8, is
You can view your link local address using the netsh interface ipv6 show
interface command. When you run this command without any additional
parameters, a list similar to the following is displayed:
For more detailed output, you can designate a connection name as a
command parameter (for example, netsh interface ipv6 show interface
“Local Area Connection 2). Using the interface parameter (with either
an interface name or an interface index number) results in the following
output, which includes the link local address for the connection:
NOTE:If you use IPv6 addresses with your array, we recommend you set
IP addresses manually on the Navigator 2 Set up Management Ports
screen. If you select Use DHCP in the Navigator 2 Set up Management Port
screen, the IPv6 address changes if you replace arrays, since the IPv6
address is created based on the array’s MAC address. This will require you
to perform the Navigator 2 search array and registration.
TIP:For the range of the IPv6 address set manually, use the global unicast
