No german ISP does this.

You know, what’s kind of encouraging is that I posted something similar to this complaint on reddit, and 100% of the responses were corporate apologia how it would apparently be so much work and so much more expensive to provide a static instead of a dynamic IP, or how routing through VPSes is so much better anyway. I hadn’t realized the reddit to lemmy brain drain was so bad, which seems good for decentralized morally good hosting.
