Your ip address is hidden. For the case of my ISP (which I trust as far as I can throw them), my traffic is end to end encrypted. This also applies if you're using someone else's internet connection and do not trust them not to snoop on you (such as your employer's BYOD wifi, or a starbucks wifi, etc)
Your IP address isn’t really a primary fingerprinting method for anybody these days. People and devices are overwhelmingly mobile, and many users will connect via the same IP.
Starbucks snooping is resolved by more ubiquitous technologies like HTTPS, DOH, and encrypted SNI.
This isn't true in my experience at least for ad tech. Finger printing has moved from a deterministic process, to probabilistic models and IP plays a meaningful role in that. I believe it is why Apple spent the time building Private Relay for instance.
