I took some interest in the concept of hashing IPs to avoid PII issues [0], and it turns out that since there's only so few IPv4 addresses, it's trivial to simply take the salt the project uses and calculate all the hashes. On my laptop it would take around two hours with the most naive implementation, so I don't really think this solves anything. This problem would be sidestepped by IPv6, but we all know how that is going so far.
