@jbz Dont look at #IPv6 as an upgrade but as maintenance. Things will just keep working fine if you neglect it, until it suddenly doesn't...

For ISP's and corporate networks, consider the damages if a certain website or resource is suddenly not accessible anymore. (because it went IPv6-only) And for online services and websites, consider availability for people who have "cheap" ISP's where CGNAT is so overloaded that it breaks.

IPv6 is not just a feature, it's availability and risk management!

🗓️ IPv6 just turned 30 and still hasn’t taken over the world // The Register

"Migration costs, complexity, and training requirements remain high, while short-term ROI is low," Gartner distinguished VP analyst Andrew Lerner told The Register. "Performance parity across applications and devices is inconsistent, and some organizations even disable IPv6 for better performance. Lack of dual-stack support in legacy infrastructure is another barrier"

Also added some beta nonsense for checking cloud providers for #IPv6 support, but it's pretty limited and of questionable utility. Would welcome some better ideas for testing such things. https://ipv6.army/cloud-tests/

Booting NetBSD 10.1 installation from floppy sets, then downloading and installing over ipv6 from an http mirror. All on a 486DX2-66Mhz.

Volle #IPv6-Unterstützung ist leider auch Ende 2025 noch keine Selbstverständlichkeit. Das betrifft auch viele Mastodon-Instanzen, dabei erstaunlicherweise auch die größte von @Mastodon selbst betriebene mastodon.social.

Und auch das "offizielle" #DockerCompose Setup [1] von Mastodon aktiviert kein IPv6.

Es geht dabei nicht um den eingehenden Traffic. Wenn euer HTTP-Proxy per IPv6 erreichbar ist funktioniert das normalerweise.

Oh true, happy 30th birthday, IPv6! 🎉

#IPv6

One of the annoyances with #NAT64 is that when some site publishes an #IPv6 AAAA record, but their IPv6 server is down and the IPv4 server is up, there's no "happy eyeballs" fallback to IPv4. Because the AAAA record exists, #DNS64 doesn't provide a mapping to IPv4.

It can be worked around by manually adding an /etc/hosts entry for the broken site.

Today's broken site is www.fsf.org. Hey @fsf - your IPv6 server is refusing connections 😉

So looking for different #Mastondon #Fediverse software as the dependencies for #Akkoma are #IPv4 only. Looking at #Misskey but will take a bit to determine #IPv6 only capability. Any input from the crowd here? I don't want to host the Mastodon suite.

When I document from now on, #IPv6 configuration will always take precedence to IPv4 configuration. Legacy should always take the back seat.
