IP Anonymization

Truncating the last octet of an IP address or hashing it — strips its status as personal data.

IP anonymization transforms an IP address so that it can no longer be tied to a specific person. Two common approaches:

1) IP truncation: the last octet is replaced with 0 (e.g., 73.45.128.91 → 73.45.128.0). 2) IP hashing: the full IP is run through a cryptographic hash (SHA-256) into an unreadable digest from which the original IP cannot be recovered.

Important for GDPR and CCPA: anonymized IPs no longer count as personal data, which means you typically don't need consent to log them for analytics. promolinks.net hashes every IP before persistence — your click logs are aggregate-only.
