@fuchsiii @malwareminigun @nik But IP addresses being PII makes no sense. For anything that is dynamnically annotated and NAT'ed the address itself will be used by thousands of people. The IP:port combination is only "you" for a brief time. Overall you could have multiple IP:port combinations over a day and someone else could be on these at other times.
If your ISP has fixed IPv4 the home router is *still* going to do NAT so the IP address only identifies an ISP account, not even a home location (my ISP, like many others, don't show up my location as where I live but a city where the peering connection is).
IPv6 without NAT would require you to know the MAC addresses of kit that an individual owns.
In all cases you need data from the ISP to map an IP address to a household or a specific user. So it's only law enforcement or hackers that could get that.
