Yeah, but fingerprinting is effective by cross referencing.

There are 1,000 people with the IP 1.2.3.4

There are 500 people with the IP 1.2.3.4 using Firefox

There are 25 people with the IP 1.2.3.4 using Firefox with a 1440p screen

There are 2 people with the IP 1.2.3.4 using Firefox with the dark reader extension with a 1440p screen at 75Hz

etc.

So rotating the IP can screw with that.
