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

- ahartmetz 6mo agoSomehow 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.
- Dagger2 6mo agoQuestions 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.
- ahartmetz 6mo agoMy anecdata is that I'm on 1&1 fiber and I have a public IPv4 address.
- Dagger2 6mo agoGerman 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.
- ahartmetz 6mo agoI'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.
