Today I found myself revisiting a prior experiment: what does the web look like when you turn off IPv4 for a day . I keep an access network available that has no IPv4 connectivity, only IPv6. As such I am able to run these tests whenever I like. I am pleased …
It had been awhile since I attended an ARIN meeting, but I recently had the chance to catch some of ARIN 56 via remote participation. While there was some IPv6 discussion, it seemed to me the bulk of the discussions were still surrounding management of the IPv4 space. The policy …
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 …
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 …
...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 …
I've been wanting to update the lab for some time so people can bring in their routers to simulate what they'll be seeing at home. This would also allow us to mock things up for ourselves without tearing apart our home networks. For now, this means DHCPv6-PD (Prefix Delegation) as …
An interesting exercise for a technical event is to see how many of its sponsors have IPv6 enabled. I have attended All Things Open (who itself enabled IPv6 on their site via CloudFlare) since its inception three years ago and will be doing so again in two weeks, so I …
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. In the IPv4 world …
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 …
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 …
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 …
I often hear comments like "Where do I start on IPv6?"; I have two answers. Anyone can turn on IPv6 at home, and then go through the free IPv6 Certification at Hurricane Electric (HE). First, find out if your ISP offers native IPv6. If you can get native IPv6, make …
As Vint Cerf said, " We need to stop running the experimental version of the Internet [IPv4], and move to the production version of the Internet running IPv6! " Do you need more reasons to use IPv6? Addresses everywhere for everything, without scarcity The number of Internet-connected devices is growing, and has …
What's wrong with NAT? NAT is often proposed as a supposedly-viable alternative to IPv6 deployment. NAT was an attempt to mitigate IPv4 address depletion , to give us time to migrate to IPv6, but not to replace IPv6. As the number of devices connected to the Internet grows , the Internet needs …
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 …
Many of my recent posts have been about sites that have not yet enabled IPv6. For those of you who have done so: Good on ya! Now, do you monitor it? I've been encountering an increasing number of web sites with AAAA records, but the addresses listed therein either do …
The response from Time Warner Cable every time I call to ask about IPv6 involves some variant on "We are not deploying IPv6 because we have enough IPv4 addresses." This response is wrong on at least three points that I would like to address here. What about the other end …
I am pleased to announce the IPv6 photo gallery is now live on our site. If you have received an IPv6 sticker at one of our presentations, or have some other interesting use of IPv6, please send us a picture! We'd love to feature it in the gallery.
In recent months, there have been presentations at some of the big Internet gatherings by Time Warner Cable engineers about IPv6-only access networks. The first was by Wes George at IEPG/IETF in October 2013 ( slides ). The second was by Lee Howard at RIPE 67 ( video , slides ). Seeing these presentations …
This week I remotely participated in ARIN 32 . This was the second ARIN meeting I have participated in. On the second day of the meeting, John Curran gave a presentation on Government Affairs and Public Policy ( slides ). In this presentation he spoke about a meeting of Internet coordinating bodies he …
If you missed my first LinuxFest talk on IPv6 Troubleshooting , you have a second chance! I will be speaking on Saturday at Ohio LinuxFest 2013 too. I think the LinuxFests want me to get out of the office to meet the community, and I'm really looking forward to it!
Who doesn't like pretty graphs? I didn't think to go back and grab the graph until Sunday morning, but this gives you a sense of how much traffic we passed through the lab in the afternoon on Saturday. The wireless coverage in parts of the main exhibit hall was a …
A little bit about how Flying Penguin came to be in a guest post on ARIN's blog: The Internet. It’s not commodity, it’s community.
Someone around here tried to convince me to go to Southeast Linux Fest 2013. Without thinking about the consequences, I replied truthfully. I said I much prefer to go to conferences when I'm speaking. Other attendees, after learning some of my strengths, ask me questions, so I'm involved in more …
My talk from last year's SouthEast LinuxFest is now available on the web. Watch on YouTube .
Join us at SouthEast LinuxFest for an interactive network lab experience. You are encouraged to: Bring your network enabled computer, smartphone, tablet, toaster, etc. to see how it works on an IPv6 network. Bring your router to get configured for IPv6 connectivity. Experienced IPv6 enthusiasts will be on hand to …
Greetings from Flying Penguin Technologies ! Stay tuned for updates about upcoming events and general musings about open technology developments.
