Network Ip Configuration - HP StorageWorks SN6000 User Manual

Network IP configuration

The IP configuration identifies the switch on the Ethernet network, determines which network discovery
method to use, and enables/disables the IPv4 and IPv6 network addressing.
An IPv4 address is 32 bits and consists of four blocks of decimal numbers, with each block separated by a
period. Each block can have up to three numbers. A single zero character displayed in a block indicates
that the block consists of all zeroes. An example of an IPv4 address is 10.20.30.40. All four blocks
contain numbers.
An IPv6 address provides a much wider range of IP addresses than an IPv4 address. An IPv6 address is
128 bits, and consists of eight blocks of hexadecimal numbers, with each block separated by a colon. The
maximum number of numerals in each block is four. One or more blocks with all zeroes are represented by
two colon characters. The total number of blocks always adds up to eight. To determine how many
contiguous blocks contain only zeroes, subtract the number of populated blocks from eight. For example,
the IPv6 address 2eee::49:24:7a:54:3434 is equivalent to 2eee:0000:0000:49:24:7a:54:3434. The
number of blocks containing zeroes in this example is two (8-6=2).
NOTE: Switches without IPv6 addressing enabled can not communicate over Ethernet with hosts or
switches using the IPv6 addressing.
