IPv6 Intelligence

State of IPv6

IPv6 Intelligence is an information source for implementations of the Internet Protocol Version 6 (IPv6). This site focuses on:

  1. Operating systems for host computers with integrated IPv6 stacks (i.e. a complete operating environment as provided by the vendor)
  2. Software packages and tools which implement subprotocols of IPv6 (stand-alone products which provide IPv6 functions not available in the integrated stacks)

Cisco IOS IPv6

By Paul Weissmann on 25 August 2009

Most of Cisco’s IOS based 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

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

By Paul Weissmann on 18 April 2009

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

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