| Internet Protocol Version 6 (IPv6) |
Overview of IPv6
SAS 9.2 introduces support for the next generation of Internet Protocol, IPv6, which is the successor to the current Internet Protocol, IPv4. Rather than replacing IPv4 with IPv6, SAS 9.2 will support both protocols. There will be a lengthy transition period during which the two protocols will coexist.
A primary reason for the new protocol is that the limited supply of 32-bit IPv4 address spaces was being depleted. IPv6 will use a 128-bit address scheme, which provides more IP addresses than did IPv4.
IPv6 includes these benefits over IPv4:
-
larger address space (128 bits rather than 32 bits)
-
simplified header format
-
automatic configuration
-
more efficient routing
-
improved quality of service and security
-
compliance with regulatory requirements
-
widespread use in global markets
