These IP addresses being released at some point, and making their way into something else is probably the reason I never got to fully run my mailserver from my basement. These companies are just massively giving IP addresses a bad reputation, messing them up for any other use and then abandoning them. I wonder what this would look like when plotted: AI (and other toxic crawling) companies slowly consuming the IPv4 address space? Ideally we'd forced them into some corner of the IPv6 space I guess. I mean robots.txt seems not to be of any help here.
