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.

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.
- interloxia 7mo agoVodafone cable's cgnat struggles. I went v6 for home so that at least the v6 sites and my own connections avoid the congestion.
- Dagger2 7mo agoIt's very common. German ISPs collectively went with DS-Lite, so most of that 77% with v6 have CGNATed v4.
- ahartmetz 7mo 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 7mo 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 7mo agoMy anecdata is that I'm on 1&1 fiber and I have a public IPv4 address.
- Dagger2 7mo 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 7mo 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.
