IPs as identifiers aren’t great: in a world of both CGNAT (more shared IPs) and a ton of sketchy residential proxies, they’ve become poor proxies for identity of a “thing”.
IPs are slowly getting worse as identifiers over time, but IP and IP range bans are like port-shifting SSH: you can often get a lot of defense against low-effort attacks for similarly low amounts of effort.
