HP-UX IPv6
Hewlett-Packard’s HP-UX Unix includes IPv6 support since about December 2001 with the bundle of HP-UX 11i and the add-on product IPv6NCF11i. This add-on software was later superseded by the Transport Optional Upgrade Releases, TOURs. IPv6 support was limited at the beginning with more features and subprotocols being added over the time with the TOURs leading to the quite sophisticated TOUR 3.0 (the minor versions are not discussed).
The most current HP-UX release 11i v3 supports most IPv6 functionality in its base system with advanced features available in the IPv6Upgrade bundle (B.11.31.0809).
The information in this page is based only on documentation, so no configuration hints can be given. The entries in the individual sections all apply to the latest IPv6 support/release.

Basic IPv6 functions
Overview
In the latest incarnations, HP-UX 11i with the latest TOUR can be used as IPv6 host (node) and router in a variety of logical (tunnels) and physical media and together with several of the newer subprotocols (Mobile IPv6, DHCPv6).
Many of the HP-UX-supplied networking utilities and programs (servers and network transports) are also modified to be IPv6-capable. Notable enhancements suggested for future (post-TOUR 3.1) versions include: MLDv2, the Advanced Sockets API and OSPFv6.7
The latest version (11i v3) supports Unique Local Unicast Addresses (ULA).
Preference
From the documentation, it was not clear if IPv6 was preferred over IPv4 (when both are available) or vice versa.
Privacy Extensions
Privacy addresses as per RFC 4941 are supported in at least HP-UX 11i v3 (B.11.31.0803 of IPv6Upgrade), for older releases no mention of temporary/privacy addresses could be found — it looks like they are not supported.
It seems support for RFC 3041 was slated for 2007+.

Packet Filter/Firewall
HP-UX includes the popular IP Filter (IPF) packet filter with enhancements to support filtering of IPv6 packets. IPv6 support is integrated into the base IP Filter on HP-UX. (The only requirement is installation of the latest TOUR 3.1 on the HP-UX below 11i v3.) IPv6 filtering functionality is equivalent to the IPv4 part — that is, stateful TCP and UDP filtering, similar filtering rules syntax and the same commands, however with added options. Extensions include filtering of the various ICMPv6 types, stateful ICMPv6 and inspection of extension headers and various tunnelling protocols.6
Tunnelling IPv4/IPv6
Configured tunnels
Configured (and automatic) tunnels as defined in RFC 2893 (and the revisited RFC 4213 in HP-UX 11i v3) are supported, since at least TOUR 2.0.
6to4
6to4 automatic tunnels as defined in RFC 3056 are supported since TOUR 2.0.
DHCPv6
DHCPv6 software for HP-UX is available as a free add-on or integrated into the latest v2 and v3 HP-UX 11i releases from Hewlett-Packard.1 The latest version is DHCPv6 2.002/2.003 (for PA-RISC and IA64 hardware platforms) and supports DHCPv6 service as client, server and relay with a variety of options, based on both stateful or stateless DHCPv6.
| Support for | Document | Title |
|---|---|---|
| Basic Stateful DHCPv6 | RFC 3315 | Dynamic Host Configuration Protocol for IPv6 (DHCPv6) |
| SIP Servers SIP Domain Name |
RFC 3319 | Dynamic Host Configuration Protocol (DHCPv6) Options for Session Initiation Protocol (SIP) Servers |
| DNS Servers Domain Name |
RFC 3646 | DNS Configuration options for Dynamic Host Configuration Protocol for IPv6 (DHCPv6) |
| Stateless DHCPv6 | RFC 3736 | Stateless Dynamic Host Configuration Protocol (DHCP) Service for IPv6 |
| NIS/NIS | ? | NIS and NIS+ configuration |
| Vendor-specific | ? | Vendor-specific options based on user class or vendor class |
Judging from the available documentation on the DHCPv6 software and its configuration files, it seems not supported are: prefix delegation; other (than DNS, SIP) server information.
PPPv6
HP-UX supports IPv6 over PPP and PPPoE conforming to RFC 2472 (PPPv6) since at least TOUR 1.0.
