When a client makes a request to the ShiftForward DMP Event Tracker system, the IP may be anonymized. This anonymization will occur as soon as it is technically feasible, before any logging or persistence takes place. There are currently two different anonymization strategies that can be applied, described in the sections below. In any case, the full IP address is never stored, unless the request explicitly disables this feature – please refer to the Event Tracking documentation for additional details.
Standard IP Anonymization Strategy
This is the default strategy for anonymizing IP events. The principle is simple: every IP found on the request will have its last octet set to 0. For example, if we have
22.214.171.124 it will become
IP Hashing Strategy
Each IP is hashed using MD5 and a secret salt, unique for each ShiftForward DMP instance.
