IPv6 address standard
Internet Protocol version 6 (IPv6) is an Internet Protocol address standard developed
by the Internet Engineering Task Force (IETF) to supplement and eventually replace
the IPv4 address standard that most Internet services use today.
IPv4 uses 32-bit IP addresses, which provides approximately 4.3 billion possible
addresses. With the explosive growth of Internet users and Internet-connected
devices, the available IPv4 address space is insufficient. IPv6 solves the address
shortage issue, because it uses 128-bit addresses, which provides approximately 340
trillion addresses. IPv6 also solves other IPv4 issues, including mobility,
autoconfiguration, and overall extensibility issues.
An IPv6 address is a hexadecimal value that contains eight, 16-bit, colon-separated
fields:
hhhh:hhhh:hhhh:hhhh:hhhh:hhhh:hhhh:hhhh
Each digit in an IPv6 address can be a number from 0-9 or a letter from A-F.
For more information about the IPv6 standard, see information about the IPv6
standard (RFC 2460) on the IETF website (http://www.ietf.org).
Storage system management interface access using IPv6
When you set up management connections in the storage system, you can configure
the system to accept the following types of IP addresses:
l
Static Internet Protocol version 6 (IPv6) addresses, IPv4 addresses obtained
through DHCP, and static IPv4 addresses
l
IPv4 addresses only
