@nygren The other thing that nobody seems to be talking about with CGNAT is there's only 65K TCP/UDP ports per address, so all you've done is delay the inevitable a little longer and potentially created a whole new class of problems while doing it. Sure, you can reduce the mapping timeouts with something like HTTP/3 / QUIC and its connection ID, but how many levels of workaround are we going to have to endure before we finally accept the #IPv6 fix?
Interesting post by Cloudflare on detecting #CGNAT as well as the performance and availability impacts to users behind it: https://blog.cloudflare.com/detecting-cgn-to-reduce-collateral-damage/ .
This re-enforces the importance for both:
1) content providers to dual-stack sites (so that #IPv6 end-users can bypass CGNAT)
2) the importance for networks to deploy IPv6 alongside CGNAT so that only a shrinking subset of traffic needs to go through CGNAT
Of particular concern is the concentration of CGNAT in the developing world, creating even more risk of a multi-tier Internet with an IPv6-centric modern internet but with other parts of the world being stuck in the past with IPv4 CGNAT.
The Cloudflare Blog · One IP address, many users: Detecting CGNAT to reduce collateral effectsIPv4 scarcity drives widespread use of Carrier-Grade Network Address Translation, a practice in ISPs and mobile networks that places many users behind each IP address, along with their collected activity and volumes of traffic. We introduce the method we’ve developed to detect large-scale IP sharing globally and mitigate the issues that result.

Hey, #IPv6 nerds - in a couple of weeks' time, it's the #UKIPv6Council Annual Meeting in #London: https://www.ipv6.org.uk/2025/10/24/annual-meeting-2025/
Tickets are free. I went last year, and it was really interesting, so I will be going again this year.
The agenda this year looks good, and it's being hosted in the #BT Tower, so we should get a good view too!
Edit: Bah, no OG on their webpage, so I've attached a picture from their Eventbrite page instead.
Wen ihr was illegales im Netz machen wollt. #ipv6 : Die öffentliche Hand kann nur legacy ip
Im Bus ist es auch besser die eigene SIM zu verwenden.

@EvolutionGnome @goetz Exactly. I file issues for everything I find that fails with #IPv6

Thank you for taking the time to reproduce this.
You probably have an #IPv4 address and default route on the host?
I can confirm that #Evolution uses #IPv6 for connecting to the servers, but only if #IPv4 is available on the host in the first place.

@EvolutionGnome
Fully agree!
I'm unable to file an issue as there is no output from any debugging option if only #IPv6 is available.
#GNOME #EVOLUTION is relying on #IPv4 being available.
Does not connect to the IMAP or SMTP server if the host is running #IPv6only
Despite France and Germany are leading the EU27 is ....

JRC Publications RepositoryInternet Standards: IPv6 standard - an analysis of uptake in the EUThe adoption of Internet Protocol version 6 (IPv6), the next version of the widely used IPv4, is key to ensure the interoperability, scalability, stability, and security of the Internet. This report provides an overview of the current level of adoption of the IPv6 protocol for Q3 2025 across EU Member States, compared to the global adoption status. The analysis uses a set of publicly available data sources, as well as data collected from our own measurements, for estimating the rate of adoption of IPv6 across two dimensions: (a) enduser adoption, i.e. end-user hosts capable of using IPv6 to connect to the Internet, and (b) server-side adoption, i.e. Internet services that can operate over IPv6.
