Welcome to the wiki for the Falling-Sky project.
test-IPv6.com is an open-sourced web site dedicated to helping end users identify whether or not their IPv6 is working; and whether specific detectable errors are found. This is meant to be useful both to end users (with reasonably friendly terminology and explanations); as well as useful to help desks (particularly, the "Help Desk" tab is meant for concise reading over a phone for tech support).
As of Feb 21 2015, this project now requires Linux. The mtu1280d daemon for testing PMTUD testing coordinates with linux ip6tables. There is no alternative at this time for other operating systems, as they lack the ability to allow user applications to filter incoming packets.
This site is open source. We encourage public mirrors; installation instructions are the the bulk of this wiki. We also encourage you to fork and adapt this for your own business needs. While we would encourage you to feed back code (or even just ideas/lessons learned), there is no legal obligation to do so.
About the name: IPv6 has been around for the last decade; however, industry has mostly ignored it. IPv4 will never run out of IP space! And the people advocating IPv6 have been considered to be at the heart of the story of Chicken Little. Now that IPv4 really is running out, and that IPv6 is really being deployed in a commercial sense, we have some need for end users to test their configuration, and perhaps get a few hints on what to do next.
