Any and all of them? Because of anonymized IP addresses in server logs? I wouldn't even buy that when it comes to the web, but certainly not to mention talking about computers and software in general, or even "tech in general", whatever that would be.

What's an anonymized IP address? As others have pointed out, there is a sufficiently small number of IP (v4) addresses that any hash function output of them can be easily brute-forced nowadays. So the only 'anonymous' IP address is the one you never collect in the first place.
