Okay, if you say so. Hotel Wifis are known for being on the bleeding edge of technology, and as the main innovator pushing new internet technology. Everything starts with hotel Wifis. /s

Exactly my point. IPv6 failed to reach the "boring, just works" level after 30 years of deployment. So much so that we are now deploying solutions with 10+ years of expected service lifetime that do not support IPv6.

Meanwhile, CGNAT really solved most issues with IPv4. Yes, even the voice/video chat issues.

Want another fun example? Try to find a SIP telephony provider in the US that supports IPv6. Go on. I do this exercise about once a year.

    /me glances over at my phone, which only has an IPv6 address when connected via cellular modem.

    /me thinks back to the decade+ of incredibly boring IPv6 service from the residential ISPs I've used.

    Sure.

    If an ISP wants to provide only IPv6 addresses to CPE, they can set things up so that happens. But if you won't be satisfied until IPv4 no longer passes over the Internet, then you're going to die unhappy about that. The goal for our lifetime is one where every residential site has a global /56 and is behind IPv4 CGN, and servers hosted by commercial entities get to choose whether they assign IPv4 addresses, IPv6 addresses, or both to their servers.

      /me searching through all the mobile network providers in Switzerland (a technologically advanced country) and not finding any.

      Seriously, this drives me mad. There is NO WAY to get IPv6 on mobile networks in Switzerland. Neither Swisscom, nor Sunrise, nor Salt, and of course no reseller.

      And Android handles this particularly poorly. I have some servers set up in my tailscale network on private IPv6 addresses, but android doesn't query AAAA addresses if it has no ::/0 route, so I HAVE to route all my traffic through my VPN which often creates other complications (with corporate wifi etc.)

      You're welcome to try to solve the challenges from my sibling post. Both of them are solved in IPv4 by a $100 router from a nearby store and with zero configuration.

    I don't get your point. IPv6 is at "boring, just works". The majority of the worlds devices run on it dual-stack and it handles a considerable amount of traffic. A lot of 5G networks run on IPv6 single stack with IPv4 compatibility on top.

    IPv6 is very much alive. And it's so boring and working so well, that you don't even notice it.

      Most of the world runs on IPv4. If we shut down IPv6 on the core routers tomorrow, pretty much nobody is going to blink an eye. And now I believe that we should do it and start again.

      The 50% stat is really mostly mobile phones on cellular networks, which remain the _only_ major success story for IPv6. Mostly because there's not enough private or even squattable IPv4 space available for many large mobile phone operators.

      Sigh. No, it's not. In a thread a couple of weeks ago, I gave several examples:

      1. You're a SOHO-type business. How can you do multiple WAN uplinks with IPv6 without NAT?

      2. How do you prevent your printer on IPv6 from breaking when your Internet connection goes down?

      For context: I deployed IPv6 in my networks in 2006. I have war stories.
