At the rate it's going, IPv6 should be ready for prime time around the same time we have nuclear fusion power plants and real self-driving cars that don't rely on a human driver.

  Well, it did go from single digits in 2014 to 40-something percent adoption in 2024. Who knows where a tipping point is, though, or the emergence of more utility for it. https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html

    I was surprised to learn from the submitted article that Discord and Reddit also don't support v6, because those two ought to have a large mobile phone userbase, and mobile networks are the biggest cases of publicly routable v6 addresses and CGNAT for v4.

      Depends where, though. Here in Switzerland I think that only one of the three main mobile operators (Swisscom) has IPv6 on their networks (and it's a 2024 thing, so not even sure it's already reaching all customers).

        Indeed. Here in New Zealand none of the mobile carriers have deployed IPv6 on mobile (and there are apparently no plans to do so) so we are at 0% for Mobile IPv6. Meanwhile all except one of the major fixed line carriers have IPv6. I don't have % figure but I would estimate >50% of fixed line connections here have IPv6 enabled (at least at the provider's end).

        Interesting, I had IPv6 on a “beta” Swisscom in 2016 or so. Crazy that it's taken them to long to productionalize it.

      Reddit is an odd half mix. It seems like most everything they have is dual stack, including the CDN and "reddit.com"... but the "www.reddit.com" page you get redirected to is itself IPv4 only (and maybe some authentication endpoints or something, I haven't looked lately). They'll probably get there shortly. Discord is an interesting one. On GitHub they've more or less straight out said "we built our backend with a bunch of hardcoded ipv4 addresses and logic and it hasn't been a priority to go back and fix vs build out the app".

    Something to consider about those statistics is that they don't include mainland China's massive IPv6 adoption, because the great firewall of China isn't going to "just" let you use Google. The Chinese government is actively pushing ISPs to deploy IPv6 to the point where [it's banning IPv4 NAT devices starting next year](https://www.lightreading.com/regulatory-politics/china-directs-telcos-again-to-speed-up-ipv6-adoption https://www.lightreading.com/regulatory-politics/china-direc...). If you do see traffic from mainland China, it'll probably be through a VPN, and VPNs tend to be IPv4-only. Most companies and servers probably won't care about Chinese visitors, but that still comes down to 763 million internet users that don't show up in the IPv6 statistics for companies like Google.

AWS provides a dual stack option that lets you run ipv4 and ipv6 simultaneously. We used it to help aid in a mostly uneventful migration over to ipv6 for most of our applications
