Understanding IP addresses
Every machine on the Internet has a unique identifying number, 
called an IP address. Computers interpret IP addresses as binary 
values of 0 and 1. To make this value easier for humans to 
understand, this binary value is expressed in decimal format as a 
“dotted decimal number”. For example, 192.168.0.17 is an 
example of an IP address.
This chapter provides a brief background about IP addresses....

Working with IP address settings
An IP address is the unique address for each device connected to the 
Internet, such as your computer or Simple Modular Storage array. An IP 
address consists of four numeric segments called “octets” that are 
separated by periods (for example, 192.168.0.100).
As you learned from installing Storage Navigator Modular 2 (Navigator 2), 
IP addresses can be static, in which case a permanent number...

Table D-1 lists the Pv6 support conditions for the Hitachi Storage Navigator 
Modular 2 (Navigator 2) graphical interface.
IPv6 link-local addresses
Based on RFC 2462, all IPv6 nodes automatically configure a link-local 
address for each interface. By default, the IPv6 protocol for the supported 
Microsoft Windows operating systems in Table D-1 on page D-5 configure...

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...

In this example, Interface 4 is an interface that corresponds to an installed 
Ethernet adapter with a link-local address of FE80::2C0:4FFF:FE19:BAD3.
Router discovery
IPv6 solves many problems related to the interaction between nodes that 
are attached to the same link. To accomplish this, an IPv6 host “advertises” 
its presence, various link parameters, and various Internet parameters 
using router discovery — an exchange of...

based interface IDs. As a public IPv6 address is a global address that is 
registered in DNS and is typically used by server applications for incoming 
connections, such as a Web server. 
This default setting can cause many temporary addresses to be registered 
in the hot, increasing processing times. Therefore, we recommend you 
check the temporary addresses and, if there are many, disable them.
To check whether a temporary...
