Unfortunately the reason is not because IPv6 is now globally available and IPv4 disappeared :( Either way, a huge thank you from my side as well, this website

Unfortunately the reason is not because IPv6 is now globally available and IPv4 disappeared :( Either way, a huge thank you from my side as well, this website has been (and still is) a very good troubleshooting tool to fix my IPv6 deployments

Something about the tone of that post is troubling me. Is it just me or does anybody else sense a bit of distress in those words? He seems to want to keep it private, though. Whatever it is, I hope he has better times ahead with the gratitude of all those who used his service.

Unfortunately, a lot of the remaining holdouts are just network engineers who just can't be arsed to learn anything new...

  We had plenty of enlightened network engineers, but eventually government wanted some torrents to stop working. Torrents were installing 6to4, Teredo and so on and hoping to work this way. But government agents were doing checks. Government agents were checking WiFi networks here and there, and ISPs. And government agents also had those torrents installed, and they could easily enable 6to4, Teredo, all of that. As soon as any such loophole permits opening forbidden website, every party gets serious fines. So they were runnning circles in panic. And blocking, blocking, blocking. That's how our dream of IPv6 died. We don't dream about IPv6 anymore. Our network engineers do learn new things. How to block. There was no DPI, now there is. A new dimension of progress.

For me personally, IPv6 still feels like something that only exists in datacenters. I've had it for ages on my servers, but never in my life have I seen a home internet connection that supports it. I'm always surprised to see that I'm using IPv6 whenever I travel e.g. to Europe.

  > [IPv6] only exists in datacenters My experience is different: Comcast has been doling out IPv6 addresses for at least a decade, at least in San Francisco. My T-Mobile phone gets IPv6 addresses. My work and my swim club also have IPv6. It's pretty awesome.

    AT&T also supports IPv6 although with comical prefix lengths. https://ssg.dev/ipv6-for-the-remotely-interested-af214dd06aa7/#:~:text=You%20are%20at%20the%20mercy%20of%20your%20ISP%20to%20have%20subnets https://ssg.dev/ipv6-for-the-remotely-interested-af214dd06aa...

      Huh? I have ATT fiber and have a /56. Edit: n/m I guess I confused PD with having a larger subnet. :(

        I have AT&T Fiber and it's been /64 since forever. I even called tech support who confirmed that they only provide /64 prefix length to home customers. How come did you manage to get a /56?

        Sorry I confused prefix delegation with with having an allocation. I have multiple /64’s. It looks like with PD you can have up to 16 subnets, so equal to a /60.

    It was "fun" discovering this the hard way a number of years ago when active US Android user count for a game we were supporting dropped 15% essentially overnight. The TCP stack in the client only did IPv4. The challenge, ironically, was convincing management that adding IPv6 was the thing worth trying. After almost a week of getting nowhere (and almost 2 weeks of outage), I forced the issue by saying "Look, I'm doing this. I need one engineer for 2 days. If it doesn't work, then it doesn't work." He got the change implemented in 2 hours. QA OKed it the next day. The topic never came up again.
