Earlier quoted context omitted.
While an IP address is not an identity, it can still zero in on a location. I suspect governments and ISPs all keep historical logs of who was assigned what address.
It can be used to identify a location, but not an individual. I assume it could be easily challenged in court (network was compromised, “i give out my WiFi to anyone who visits my home”) without other supporting evidence.
To keep the discussion interesting, please do not assume or guess, thanks!
