IP bans by modern services like CF can't be solved that easily in my experience.

  Clearly CF has a crystal ball /s. Once the IP address I don't own is released and assigned to some other router how do you think CF determines the new IP address for the individual/home? Unless this person is running the CF Dynamic DNS service which gives CF the IP address, I'm not sure CF would have any reasonable validation techniques to determine who is what given the size of residential networks.

    Cookie on their validation page? Browser fingerprint hopping IPs in the same block?

        So i've turned cookies off and switched to my ipad to browse the internet for the evening, they have no fingerprint, and no cookie... now what?

        Are you on a different IP block? ISPs sometimes just switch the last number. I had to use a VPN (a whole new IP) and clean chrome install to bypass one those "IP blocks" which was combined with fingerprinting.

        It's random. I've been on 24.x.x.x, 66.x.x.x, and 98.x.x.x. https://postmaster.comcast.net/dynamic-IP-ranges.html https://postmaster.comcast.net/dynamic-IP-ranges.html

(Author.) My ISP only rotates IPs when they reboot their central equipment. Not enough to do it on my end.

  With some ISPs, they will issue a new IP if you change the router's (WAN) MAC address. Might be worth a try next time (crossing fingers you don't need it).

    This is what I've always seen too. I've never seen a residential ISP that allocates static DHCP addresses, they typically allocate in days which is why many people can maintain a leased address for months on end. Once you go offline though, all bets are off. Every ISP can determine if the subscriber is disconnected and if they are, they're going to reallocate your address. To your point, once the MAC address is changed, they have to issue a new IP address because using the logic posted above, the other address is allocated to a different MAC.
