IPv6 Intelligence

Cisco IOS IPv6

Paul Weissmann

Most of Cisco IOS routers support a very broad range of IPv6 features and subprotocols with the right IOS version. This page compiles basic information on the various IPv6 capabilities of the IOS 12.2T and 12.3 and 12.4 release trains.

The information is mostly based on the exhaustive Cisco documentation and checked with the results of Defense Information Systems Agency/Joint Interoperability Test Command (JITC) compliance tests. Since IOS releases generally have the same feature set across different routers and product families the remarks here should apply to other Cisco systems running the same IOS versions as well.

Connectivity

Paul Weissmann

Several updates regarding operational issues, including connectivity. After a short transition period, this site changed its IP connectivity and URL — it is now reachable at ipv6int.net; a HTTP redirect is configured for the old URL.

On a sidenote regarding IPv6 access — we're seeing a constant month-to-month ratio of about 8-11 percent of visitors accessing this site over IPv6. For comparison, at our sister site OpenPA.net about 1 percent of all accesses come over IPv6.

Operating systems IPv6 conformance — JITC

Paul Weissmann

Several operating system pages have been updated with IPv6 protocol conformance/RFCs, including:

Solaris 10
Windows Vista SP1
HP-UX 11i v3
Linux 2.6 — the data from two distributions has been used for this — there will probably be no single representative “Linux IPv6 compliance”

The information is based on test and conformance documents from the Defense Information Systems Agency/Joint Interoperability Test Command (JITC) Approved Product List.

DHCPv6 software updates

Paul Weissmann

Several additions and updates to the DHCPv6 section, including the addition of an overview comparison table.

ISC DHCP DHCPv6 includes support for DHCPv6 server, client and relay since version 4.0, updated in the current 4.1.0, for Linux, BSD and Solaris systems
Linux DHCPv6 projects aims for DHCPv6 server, client and relay support for Linux systems
The other DHCPv6 pages have been updated and brought up to date

With thanks to Derek Morr for the pointers.

Various pages updated with current documentation and releases

Paul Weissmann

After a long hiatus new IPv6 information was collected for various operating systems and software packages. This includes:

HP-UX 11i Unix, adds new IPv6 features in the 11i v3 release with optional IPv6Upgrade package
Apple Mac OS X, adds no new notable IPv6 features in the 10.5 release, but enhances application and system services IPv6 support
Dibbler DHCPv6 software, adds various news features and options for the DHCPv6 protocol in the latest 0.7.3 version
WIDE DHCPv6 package did not add any notable new features in their latest 2008 releases

Solaris/OpenSolaris DHCPv6

A DHCPv6 client made its way into OpenSolaris (actually quite some time ago) and, more recently into commercial Solaris (update 8/07). It supports stateful DHCPv6 client functionality.

Hewlett-Packard HP-UX IPv6

Hewlett-Packard's Unix derivate HP-UX supports IPv6 in various stages since December 2001. The new HP-UX IPv6 page describes the various software packages and HP-UX 11i releases with their corresponding IPv6 support. The information is compiled from available documentation.

New Dibbler DHCPv6 Software Version

The Linux and Windows DHCPv6 software Dibbler is available in a new version—0.60. It was released in July and features updated and enhanced support for various DHCPv6 options and RFCs. Read the full page for more and detailed informations.

IPv6 Connectivity

Operational note: internecine.eu can now also be reached via IPv6. Connectivity (in the form of a tunnel—no native IPv6 yet) is kindly provided by SixXS.

Your friendly NOC.

Launch of the IPv6 Resource—internecine.eu

Start of the IPv6 Resource with the first core content. Provided is information on verified IPv6 functionality from selected Operating Systems and Software packages and tools. The content is originally based on a diploma thesis, converted and restructured into an online resource. More content will be added soon, as time permits—starting with a completion of the rest of the thesis' content.
