As predicted I got moved to AS14593 and #IPv6 is gone.
So https://starlink.awlnx.space is no longer operational.

"IPv6 is easy but it just takes time until everything is ready." For the second time, since @ripencc@twitter.com started allocating IPv6, a request for a subsequent /29 allocation was granted. Read NetCologne's (@NetCologneNEWS@twitter.com) #IPv6 story on #RIPELabs:

Probably https://starlink.awlnx.space/ will go away in the next couple of days.
As #Starlink migrates to AS14593 #IPv6 connectivity will be lost.
Let's see when it returns.
Solution: Dual-stack IPv4/IPv6 is not supported. Block #IPv6.
What a great solution from @Fortinet@twitter.com.
I was wondering about #IPv6 support in @NordVPN@twitter.com. The proposed autocompletions don't look promising. 🤨
RT @kistel@twitter.com
Perhaps the IPv4 - #IPv6 transition is like analog-digital photography was a decade ago. Yes you can still use the old kit but the world is moving on. Some tools (eg. lenses) you can keep using without change, but there are fundamental internal differences. Resistance is futile!

V tichosti se @Alzacz@twitter.com stala dostupnou po #IPv6. Díky @Cloudflare@twitter.com. 👍🏻
Proč ale používají Cloudflare funkci pro přepis IPv6 adresy na Class E IPv4 (https://blog.cloudflare.com/eliminating-the-last-reasons-to-not-enable-ipv6/)? Ztrácí se tím IPv6 adresa klienta a navíc to zjevně web Alzy i uživatele mate. 🤔

Hey, @Glosbe@twitter.com, your web servers do not listen on #IPv6, even though it is in the DNS. Therefore everyone on IPv6-only sees your website like this:
Do you want to help persuading people to deploy #IPv6? We still have an open position. When applying, don't forget to mention my name. 😉

Spustit službu na dual-stack je polovina řešení. Tou druhou, složitější, je měřit na obou protokolech a data rozumným způsobem agregovat.
Zvlášť v době CGN mohou být problémy pouze s IPv4, zatímco #IPv6 může fungovat správně. Tunelování IPv6 může zase způsobovat opačné problémy.

We have a new online course in the #RIPENCC Academy - and it's all about #IPv6 security! Understand common security threats to IPv6 and how to counter them, and learn how to develop a high-level security strategy. Get started at:

Our latest step towards full #IPv6 deployment has been to switch the management interfaces for our #DNS servers in London over to IPv6 only – both for K-root and our Authoritative DNS service. Read how and why we did this in this @ripelabs@twitter.com article:
