This IPv6 Toolkit allows you to perform security assessments and trouble-shooting of your IPv6 network. A new version has been released recently.


This toolkit is maintained and further developed by SI6 Networks . The philosophy behind the toolkit is to provide an interface between "your ideas and an IPv6 network" as illustrated in the image below:

SI6 Toolkit Philosophy

The main goal of this toolkit it to provide security analysis and trouble-shooting functionality for the IPv6 protocol suite. The toolkit consists of 12 individual tools and supports the latest versions of the following operating systems: Linux, FreeBSD, NetBSD, OpenBSD and MacOS. The toolkit has been released under the GNU General Public License (GPL).

New release

We are pleased to release the SI6 Networks' IPv6 Toolkit v1.3 .1 . On the toolkit side you can find the tarball , a PGP-signed version of the toolkit, a link to the toolkit's GIT repository and other useful information.

This release contains a number of new features:

  • It includes a full-fledged IPv6 address scanning tool (scan6) - probably the only comprehensive IPv6 address scanning tool out there.
  • It includes support for tunnels (in most of the tools). If you are currently employing a free IPv6 tunnel to connect to the IPv6 Internet, you willl now be able to play with the tools using your tunnel.
  • It includes features that have been in our "to do list" for a while:
    • Manual pages in troff format for all the tools
    • A makefile, to easily build and install the tools, configuration file, manuals, etc., on your local system

Please send any bug reports and/or feature requests to fgont [at] si6networks [dot] com

Fernando Gont presented this toolkit at the IEPG during IETF 85 in Atlanta, US. The slides are available on the IEPG web site.
