    Correct me if I’m wrong but ISPs dynamically assign WAN IPs to the vast majority of their non-enterprise consumer base, right? If that’s the case, how would historical posts on 4chan have any relevant data to dox someone with? Wouldn’t the window of opportunity have passed for pretty much everything older than a few weeks?

      Every ISP I’ve dealt with thus far has kept me on the same dynamic IP for years on end.

      Only once did it actually change for me, and it was seemingly random so I assume they must have updated the lease block range.

      It kind of makes sense because if some 3 letter agency asks for a historical lookup, they have less data they need to store compared to constantly rotating IPs to everyone.

        This is highly dependent on where you are, and your ISP. I get new IPs basically daily. Even my ipv6 prefix changes daily for no reason other than to be annoying I guess. It’s infuriating, but somewhat convenient for privacy reasons (only).
