I guess that means able to access services on the Internet over IPv6, not me being able to get a /64 and providing services myself to others.
Sort of ok for phones I guess, although not as great if someone doesn’t have access to fiber and have to use a mobile link in a residential environment.
Bahnhof actually just provides NAT:ed fiber connections as well as default, but will issue a public, unique IP if asked (at no additional cost).
