> If I now run a `for` loop over all IPv4 addresses and write them to my HDD, am I suddenly illegally storing personal data of all the people behind those IP addresses That's actually a good point. The IPv4 space is pretty limited. I guess the GDPR law makes it PII if you bundle both the IP with an action made by that IP (e.g. that IP visited that website).
