Subj : IPv6 in 2021 To : All From : Michiel van der Vlist Date : Thu Jan 06 2022 02:26 pm As published in Fidonews... IPv6 in 2021 By Michiel van der Vlist, 2:280/5555 Another year has passed. When we compare the statistics as published by the end of 2020 with those of today, we see that IPv6 in Fidonet has grown again. From 93 to 103 nodes. 110 -| -| . 100 _| _| . 90 _| _| . 80 _| . _| 70 _| . _| 60 _| _| . 50 _| _| 40 _| . _| 30 _| _| . 20 _| _| 10 _| . _| . 0 _|__.____________________________________________________________ | | | | | | | | | | | 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2021 was the year that that we passed the 100 mark. In May Shelley Petersen of 1:134/102 was listed as #100 in the list of Fidonet IPv6 nodes. Shelley's system is listed with the INO4 flag. It can only accept incoming calls via IPv6. It has this in common with the system of Brandon Moore, also of net 134. Something else that is remarkable is that these nodes have an IPv6 address in the same /64. They share that same /64 also with 1:134/100 1:134/101, 1:134/103, 1:134/301 and 1:134/302. Frankly, I do not know what to think of that... 2021 was also the year that it was ten years ago that the first IPv6 connection in Fidonet was made. On 1 November 2011 Andre Grueneberg of 2:2411/525 made an IPv6 binkp connection with Benny Pedersen of 2:230/0. It was Andre Gruenebrg that added the IPv6 code to binkd. A trend we do not really see continue is the move towards native IPv6. In 2021 34 of the 103 nodes used a tunnel. About 1/3. This has been more or less constant over the past five years. In 2017 it was 22 out of 64. Over the years The ratio remains at about 2/3 native, 1/3 tunnel. This is not what I expected and goes against the general trend on the InterNet that native IPv6 is slowly gaining foot and replacing transition mechanisms such as tunnels. Maybe what we are seeing is that the Fidonet Pioneer Spirit is still here and that sysops do not want to wait for providers to support native IPv6 and take things in their own hands by setting up tunnels. Now that tunnels have been mentioned: I also could not help noticing that of these 34 tunnels, only one is not a he.net tunnel. Until 2017 there was SixXs as alternative free tunnel service, but the main driving forces Jeroen Massar and Pim van Pelt got tired of it. And now he.net is more or less the only game in town. I wonder how long they will continue with this wonderful free service. If they stop it will certainly have an impact on Fidonet. The very fact that a third of the IPv6 sysops still uses a tunnel shows that we still have a long way to go. I know of one sysop that has native IPv6 from his provider but who uses a he.net tunnel because that way he has a static IPv6 pefix, but that is the exception. Normally when native IPv6 is available from the provider one does not use tunnels any more. So there is still a substantial amount of InterNet providers that do not offer native IPv6 to their customers. As I write this, Delta Fiber, a relatively small company on a world scale will start digging in my area. The planning is that I will have FTTH third quarter 2022. The snag is that they do not offer native IPv6. They say they will eventually, but they will not give a time frame, so I do not know if/when I have functional FTTH if it will offer me IPv6. Over ten years ago I told myself I would not buy new network equipment that does not support IPv6. Now I have a problem. There is no competition. It is Delta Fiber or no FTTH. If I go ahead with them now, the installation is "free". If I want it later, there is a EUR 650 installation fee. It makes sense, calling back the digging crew is expensive. I want FTTH, but I also want a provider that offers native IPv6. So I compromised. I took the cheapest subscription for a year. It is cheaper than the EUR 650 installation fee. If they still do not offer IPv6 at the end of the first year, I say goodbye to them and stay with the cable company that has been offering me native IPv6 for the last five years. Or... maybe I will reconsider, go back to he.net, show my sage badge and ask for a tunnel again. To be continued... I noticed something else. For the purpose of keeping the weekly published list of IPv6 nodes up to date, Kees van Eeten and I actively hunt for new IPv6 nodes. Kees runs a script that hunts for AAAA records in host names in the nodelist. Whenever he finds new AAAA records, he informs me and I try to make an IPv6 connect. If successful, I add the node to the list. If the IPv6 connect fails, I try to make contact and help the sysop to make the system reachable over IPv6. Sometimes this is successful, sometimes it is not. Remarkable is that ever so often the sysop has no idea how the AAAA record got to be there in the first place. Someting else I do not know what to think of. Other than that, 2021 was not all that eventful regarding IPv6. Not for Fidonet en not for the Internet in general. We saw steady growth but we can't say that IPv6 is the dominant protocol yet. Can we get rid of ipv4 yet? Obviously not, certainly when Fidonet is concerned. But I ran across an article from SIDN (Stichting Internet Domeinnamen Nederland) (Dutch registry for Internet Domain Names Netherlands). https://tinyurl.com/3xe4dc5a It is about an experiment where IPv4 is switched off completely. In order not to have to tell the same story over and over again, I sometimes refer people to Fidonews articles I wrote in the past. Since there seems to be no easely available searcheable archive, I made a list of these articles. I hope I did not miss any.
