No german ISP that i know of does this, it’s awful. One doesn’t even offer reverse IP ptr entries whatsoever, even if you had a static IP.

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.

Personally, I find it hard to believe that just not changing somebody’s prefix all the time would possibly cause so much technical extra effort that any additional fee is justified.
