I have been feeling like it was time to do something with SixSpotting again recently, but it was someone asking out on Mastodon how old the game was that led me to dig in further. It turns out the very first checkin was on 2014-05-21. SixSpotting is now officially 10 …

Blog migrated
It is understandable if you thought Flying Penguin Technologies was all but defunct based on the lack of activity on this blog. I have still been doing the IPv6 Evangelist thing, albeit mostly over in the Fediverse these days. Nevertheless, the FPT infrastructure has been maintained all this time in …
IPv6 with macvtap and libvirt
From the "I wish I'd have known that earlier" files:
I'm posting this here in the hopes of saving some folk the trouble of running this down.
If you are trying to use
macvtap
onto an existing adapter for a libvirt guest and you're having odd problems with dropped IPv6 …Getting DHCPv6 delegation working
...or "How I learned to make friends with duct tape"
Last week I wrote about not being able to route delegated prefixes as none of the servers seemed to have functionality to update the routing table. Shortly after tweeting this, a colleague replied with a way forward. In case Twitter's …
FAIL: Serving prefixes with DHCPv6-PD

The use of the colon as an address separator in IPv6 has caused some mild annoyances over the years. Microsoft created unique solution, essentially mapping colons to dashes and putting this in a top-level domain. They chose ipv6-literal.net and implemented this internal to their software.

Retrospective: IPv6 Utility
When I first started my journey to learn IPv6, I could not get native IPv6 at home from my residential ISP. Undeterred, I went to Hurricane Electric; HE offers both an IPv6 certification program that's a great place to start to learning how IPv6 works, and free IPv6 tunnels. I …
Mission: Possible
You've probably seen our mission statement: "Promoting the adoption of IPv6 for the preservation of an open Internet." Mission statements seem to be a dime a dozen these days, so let's look at just how important this work really is.
At the All Things Open conference last year, one of …
Troubleshooting with ping6
At work today, I helped someone use
ping6
to figure out what to fix on a server that wasn't reachable over IPv6. I have a pretty basic formula that I thought I would share.I will use this information for the problem host:
nethope@fixme$ ip -6 address show 1 …
