Noch darf gewettet werden.
Wird der Temperatur- und Feuchtigkeitssensor von Shelly auch seine Arbeit in einem #IPv6only WLAN verrichten?

Those roaming regulations are great and I love them! I was in France when SMS roaming regulations came into force. Had to pay 39ct per text when I arrived. When I left, it was down to ~9 cents.
Buuut I still have a question:
When will there be compulsory #IPv6 support in data roaming? There are several networks that turn off #IPv6 while roaming. Some even lack #IPv6 entirely.
My mail server is #IPv6only which means that I don't have access to my e-mails while roaming!
If you can load the following domain, you have working IPv6 and a DNS resolver that has IPv6 support.
breaking news
(I have to confess apple is sometimes good)
given a #IPv6only mobile access (like the Deutsche Telekom within Germany, not during roaming)
recent apple #iOS 18.5
makes
#IPv6mostly for clients via hotspot
#dhcpoption108 as well #pref64
I made also the windows test - in case option 108 is not provided by the client, iOS provides IPv4

Jupp. Wobei mir das in Verbindung mit den sinkenden Preisen Hoffnung macht. Inzwischen werden #IPv4-Adressen wieder für nur 20$/Stück verkauft. Wenn das weiter runter geht, steht irgendwann wirklich #IPv6only vor der Tür.

"Swisscom’s mobile services deliver reliable and highly
secure coverage in Switzerland and internationally.
Among the two primary mobile services, voice and data,
Voice over LTE (VoLTE) already utilises IPv6. With the
introduction of a Dual Mode 5G Mobile Core in 2025,
we are laying the foundation to ensure that in 2026,
Swisscom’s entire mobile offerings will be either
IPv6-only or at least IPv6-first."

@Jarek @landley that assumes #IPv6 addresses are static (Providers in #Germany do "pseudostatic" alike #IPv4 and unless one's a business customer, will forcibly disconnect once each 24 hours and reassign a new IP) and that applications ain't configured to prefer IPv4 over IPv6 just to avoid timeouts and having to check if IPv6 exists since the only "#IPv6only" #ISP I know is #Starlink (and even they do #CGNAT due to customer complaints…)
Nice! @tailscale finally updated their infrastructure to support IPv6-only OIDC endpoints (after I complained)
#WhatsMissing: A tool to check if #TorBridges are still available/online/reachable that one can use either #standalone (with #TorBrowser and/or #Tor Expert Bundle) or on @tails_live / @tails / #Tails.
- Cuz I do run into issues and kinda want to sort #Bridges by availability so I don't waste time on a #TorBridge that is down and also thin-out the list of bridges that ain't online anymore.
Whilst I do acknowledge that @torproject do disrecommend having a huge list of Tor Bridges on hand, I do regularly need them for contacts who are behind a #GreatFirewall and can't #SSH-Tunnel out of it.
- Sadly #BridgeDB doesn't offer good #filtering options so one can't just query types effectively like "I need #webtunnel on #IPv4" or "I can only use Ports 80 & 443 on #IPv6" which may work.
Espechally being able to filter for #IPv4only and not just #IPv6only is something I miss, alongside the filter for #PluggableTransports type as @guardianproject #Orbot seems to only handle #obfs4 and not webtunnel or #meek at all...
- I'm pretty certain that merely pinging a bridge at it's port isn't working as a shure-fire way to check for it's availability.

I just set up a backup Internet connection on a customer's firewall, and since their applications require IPv4 while the connection is #IPv6only, I set up a CLAT on the backup router since the ISP does 464XLAT. 
The only drawback is that the usable MTU for IPv4 has been reduced by 40 bytes, but for a backup link that only has an #IPv6 prefix, I think that's a fair tradeoff.

Dear followers,
Please:
Test devices and services in your area for #ipv6only (with DNS64 or without) and write to the manufacturers/operators if it doesn't work!
Sometimes you're successful, often not.
But the more people do it, the higher the chances of success!
Liebe Follower,
eine kleine Bitte:
Tested in eurer Umgebung Geräte und Services auf #ipv6only (mit DNS64 oder auch ohne) und schreibt die Hersteller/Betreiber an, wenn es nicht geht!
Manchmal hat man Erfolg dabei, oft auch nicht.
Aber je mehr es tun, desto höher sind die Erfolgschancen!
