IP addresses Panopticlick does not log IP addresses, but we do compute cryptographic "keyed hashes" or HMAC s of each IP address, using a key which we periodically discard. This hashed IP will allow us to collect an anonymous dataset about how often browsers that change IP address could have been followed using a fingerprint.
