I wonder why Germany has a relative high adoption rate with 77%? They are normally behind when it comes to new technology. Is it because they have more carrier NAT? In Denmark I can get cheap 1 / 1 Gbit/s fiber, but still no ipv6 :(

Carrier-grade NAT for home connections is pretty rare in Germany. I only know of Deutsche Glasfaser - a fairly new ISP that isn't doing too well.

  Vodafone cable's cgnat struggles. I went v6 for home so that at least the v6 sites and my own connections avoid the congestion.

  It's very common. German ISPs collectively went with DS-Lite, so most of that 77% with v6 have CGNATed v4.

    Somehow it's really hard to find numbers, but AFAIK at least Telekom and 1&1 don't use CGNAT for home connections, which already rules out that 77% have it.

      Questions like this suggest that 1&1 do: https://forum.openwrt.org/t/solved-dsl-over-ds-lite-with-isp-1-1-destination-port-unreachable/185517 https://forum.openwrt.org/t/solved-dsl-over-ds-lite-with-isp... I'm less sure about Telekom. For obvious reasons, it's hard to find info in English.

        My anecdata is that I'm on 1&1 fiber and I have a public IPv4 address.

        German ISPs commonly seem to have an option of their "old" platform (v4 only, no v6) or their "new" one (v6 and CGNATed v4). Maybe you're on their old one? Or maybe they only use it for certain account tiers or somesuch.

        I've been with 1&1 for a long time, previously DSL and VDSL, so I could have something grandfathered in - but I doubt it. Especially after the recent transition to fiber. And I am not paying for any special options.

We have enough IPv4 addresses (combined with CGNAT) in Denmark so the providers have no business incentive to spend money on supporting IPv6 :/
