> the ISPs want a stateless solution, so customers get a dynamic prefix. Maintaining the same prefix across power outages needs a stateful solution, so only business plans offer them for an extra fee, much like static ipv4 addresses. I'm surprised based on my experience: in 15 years of residential IPv6 usage I've always had the same IPv6 prefix (for a given ISP contract of course), even for those ISPs that insisted on handing out dynamic IPv4 with no option for a static one plus had no qualms renewing the IP at any moment, not just power down. > stateful solution I'm seeing this the other way around: dynamic needs lease tracking while static just needs a permanent record attached to the already present auth mechanism.

My experience is the opposite!

My ISP-given IPv6 (/57 for whatever reason) prefix is also stable, however beware that, at least on my OpenWRT based router, the option to release the prefix back to the ISP when the router is shut down is checked by default. I discovered this when I rebooted for a firmware update and when it came back up my network had renumbered itself.

  Comcast started rolling out IPv6 in 2011

  Can't recall the exact timeline but: - I think Free had it since forever and a half, although IIRC it was some weird 6rd or something. Freebox v6 (2011) for sure had it, v5 (2006) may had supported it from the start and for sure supported it down the road, I think v4 could have had it too through an update at least but honestly can't recall. - Orange in France had a public opt-in experiment for native IPv6 over ADSL to which I enrolled at the time. - Then I lost IPv6 because I moved to a cable operator which did not support DOCSIS 3.0 (a requirement for IPv6 on cable connections) at the time. - After that FTTH rolled out and basically every ISP provided native IPv6 on it from the get go. Non-biz IPv6 support in France is sitting in the ballpark of 99% these days, both residential and mobile. National regulations helped a lot. Residentially there has been a huge plan towards a national FTTH rollout, including in remote areas (the idea being that no one should be cast aside of a full speed internet); this plan also had specific requirements to enforce competition to prevent regional or local monopolistic situations such as the one that historically happened with cable operators (or like the ones I keep hearing about in the US). For mobile it was simpler: you want a radio license for 5G? you have to support IPv6, or else.
