Support for RFC 4291 (IP Version 6 Addressing Architecture)
RFC 4291 defines the addressing architecture of the IP Version 6 (IPv6) protocol. The
B.11.31.0809 version of IPv6 updates the HP-UX implementation of IPv6 addressing
architecture from RFC 2373 (IP Version 6 Addressing Architecture) to RFC 4291.
NOTE: Anycast address support is not available in the B.11.31.0809 release of IPv6.
It is available in the B.11.31.0907 release of IPv6.
Support for RFC 4213 (Basic Transition Mechanisms for IPv6 Hosts and Routers)
RFC 4213 specifies mechanisms that IPv6 hosts and routers can employ to interoperate
with IPv4 hosts and routers while utilizing the existing IPv4 routing infrastructure.
The B.11.31.0809 version of IPv6 updates the HP-UX implementation of IPv6 transition
mechanisms from RFC 2893 (Transition Mechanisms for IPv6 Hosts and Routers ) to RFC
4213.
