IPv6 in 2025
By Michiel van der Vlist, 2:280/5555
Another year has passed. When we compare the statistics as published
by the end of 2023 and 2024 with those of today, we see that there is
little or no growth. The number of Fidonet IPv6 nodes keeps hoovering
around 110. On 31 December there were 116 IPv6 nodes. Considering that
Fidonet a s a whole has stopped growing a long time ago and is now
shrinking that isn't really bad.

Outside of Fidonet IPv6 continues to grow. Slowly but steadily. Accor-
ding to Google worldwide IPv6 adoptation now hoovers around or just
under 50%. Almost half of those visiting Google do so via IPv6.
https://www.google.com/intl/nl/ipv6/statistics.html
Some even claim the tipping point has been reached where IPv6 is now
the norm but I would say this is premature.
Back to Fidonet.
The number of Fidonet IPv6 nodes that still uses a tunnel dropped from
a quarter to a fifth. Nearly all of them via he.net, but a few via
another tunnel broker. So there is improvement but there are still too
many ISPs around that do not support IPv6. Shame!
The number of nodes carrying the INO4 flag dropped from 3 to 2. So the
vast majority of Fidonet still supports full IPv4. Not really what I
expected, but that is what it is. What I expected was that providers
switching their customers to CGNAT would have resulted in much more
IPv6 only nodes. But that obviously did no happen. Yet. That does not
mean CGNAT did not happen and that it is not a problem. With the
coming of FTTH (Fibre To The Home) especially here in Europe we see
many new ISPs that do not have lots of "historic" IPv4 and who do not
have, or do not want to spend, large sums of money to buy IPv4 on the
market. So they use CGNAT to have their customers connect to the IPv4
internet. Some of these providers - like mine - give customers the
option to get an IPv4 address outside the CGNAT pool and some don't.
But Fidonet sysops are resourcefull and they look for work arounds. In
Germany there is feste-ip.net that jumped in the gap. They provide
IPv4 access to servers run at home via an IPv4 to IPv6 port forwarder.
I mentioned that in my article titled "DS-Lite: a solution" in FN
34:33 Aug 2017. Some Fidonet sysop are using this or a similar service
to deal with CGNAT.
Another remarkable development is that a number of Fidonet systems
advertise IPv6 capability via an AAAA record on the host name in the
nodelist, but they dot not actually support IPv6. Dmitry Protasoff
maintains a system that (among other things) monitors the nodelist
for systems that advertise IPv6 capability.
https://nodelist.fidonet.cc/analytics/ipv6
Compare that to the list of nodes That advertise IPv6 but are actually
IPv4 only:
https://nodelist.fidonet.cc/analytics/ipv6-advertised-ipv4-only
So some 20% of the nodes advertising IPv6 connectivity do not actually
support it. One of the problems with dual stack is that if one of the advertised connection mechanims fails, it can take a long time before
it is discovered. Most applications just fall back to IPv4 if IPv6
fails. That includes nearly all binkp capable mailers. Winpoint is the
odd exception.
This large number of nodes that advertise IPv6 connectivity but that
do not actually support it is a bit of a mystery to me. My impression
is that many of those sysops are not even aware of the situation.
They make use of he services of a DNS provider that supports DDNS
and they get an IPv6 address assigned by default. Of which they do
not seem to be aware and so they do not configure their systems to
accept incoming IPv6 calls. This is a bit of speculation as most of
the sysops concerend do not respond to netmail, the systems seem to
run on autopilot.
Another phenomenon that may have existed for some time but that only
recently emerged from Dmitry's statistics is that there are a number
of nodes who's IPv6 reachability is unstable. One day they have IPv6
and the next day they haven't. To be back again after a couple of
days.
https://nodelist.fidonet.cc/analytics/ipv6-weekly-news
I have no explanation but the fact many of these nodes reside in
regions 46 and 50 suggests it may have to do with the war going on in
Eastern Europe. The observed instability may or may not be
specificallly linked to IPv6, it may affect their IPv4 reachability as
well, but that was not investigated.
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.
