IPv6 Release Notes

Support for RFC 3484 (Default Address Selection for Internet Protocol version 6 (IPv6))
A typical IPv6 host can be assigned multiple addresses with different characteristics,
such as link local address, global address, temporary address, unique local address,
special purpose addresses for IPv4-IPv6 transition. Additionally, if the host is dual-stack,
it is also configured with IPv4 addresses. This leads to multiple possible source and
destination address choices while initiating communication. It is preferable to have
default algorithms common across all implementations for selecting source and
destination addresses. RFC 3484 specifies such default algorithms and address selection
policies to make the address selection predictable.
NOTE: The configurable policy table 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 3493 (Basic Socket Interface Extensions for IPv6)
The B.11.31.0809 version of IPv6 updates the HP-UX implementation of basic socket
interface extensions for IPv6 from RFC 2553 (Basic Socket Interface Extensions for IPv6)
to RFC 3493. As a result of RFC 3493 support, the IPV6_V6ONLY IPv6 level option is
available to restrict IPv6 communication with only IPv6 nodes.
Support for RFC 4584 (Extension to Sockets API for Mobile IPv6)
RFC 4584 specifies API support for Mobile IPv6 applications to retrieve and set mobility
related information in the extension headers and destination options.
NOTE: The B.11.31.0809 version of IPv6 does not support the setting and sending of
type 2 routing header and home address destination option. Although HP-UX does
not support setting or sending of type 2 routing header, HP-UX continues to support
receiving of type 2 routing headers.
Support for RFC 4193 (Unique Local IPv6 Unicast Addresses)
RFC 4193 specifies the guidelines and usage of unique local IPv6 unicast addresses that
are globally unique and are intended for local communications only. These addresses
are a replacement for site-local unicast addresses.
NOTE: The HP-UX DNS server requires manual configuration of the d.f.ip6.arpa
zone as described in RFC 4193.
Support for RFC 4443 (Internet Control Message Protocol for IPv6 (ICMPv6))
RFC 4443 describes the format of a set of control messages used in the Internet Control
Message Protocol (ICMPv6) for IPv6 . This release updates the HP-UX implementation
of ICMPv6 from RFC 2463 to RFC 4443.
