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 …

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
macvtaponto 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

At the All Things Open conference last year, one of …
IPv4 crutches
Back in June I participated in Turn off IPv4 Day as a show of solidarity. I had grand plans to write up a long post about the issues encountered throughout the day, but I had already done similar versions of this activity in the lab, so there weren't a whole …

The other day on IRC, the bot for one of the channels I frequent reconnected, and I noticed it was coming in over IPv4. I knew the host it was on is IPv6 capable, so I jokingly asked it "y u no ipv6?". The bot's owner told me "patches welcome …
