IP client addresses can and do change, be it that they move from landline to mobile or cafe wifi etc. I doubt many use the IP address to track clients for an extended period of time (one hour? one day?).
There are better tools for tracking, like cookies, session IDs, anything that client software voluntarily sends with some request of any kind. Nowadays even with least trackable protocol possible, DNS, as of DNS-over-HTTPS...

- pilif 8y agofor the last 10 years or so, every single OS out there randomises the lower bits by default and even rotates it every few connections. The thing that remains static is the prefix you got from your ISP but that works in exactly the same way as your v4 address you get when you connect.
