Understanding Calls to the Demdex Domain
Audience Manager and the Adobe Experience Platform Identity Service make calls to and receive data from the demdex.net
domain. This may seem like Adobe is working with an unusual third-party domain, but this is not the case. This section describes the elements in a demdex.net
call.
demdex.net
demdex.net
calls (e.g., dcs.demdex.net
, fast.demdex.net
, etc.). Regardless of the prefix, a call to something.demdex.net
is always a call to Adobe and not to some unknown or suspicious third-party domain.dpm
DPM is an abbreviation for Data Provider Match. It tells internal, Adobe systems that a call from Audience Manager or the Adobe Experience Cloud ID Service is passing in customer data for synchronization or requesting an ID. This is the most common demdex.net
call you’ll see from Audience Manager or the Adobe Experience Cloud ID Service.
DPM call basics:
- Audience Manager: A DPM call from Audience Manager sends data to the Data Collection Servers and Profile Cache Servers. See Data Collection Components.
- Adobe Experience Cloud ID Service: A DPM call from the Adobe Experience Cloud ID Service is a request for a visitor ID. See Cookies and the Adobe Experience Platform Identity Service and How the Adobe Experience Platform Identity Service Requests and Sets IDs.
Note: Adobe Experience Cloud ID Service customers can change the DPM prefix in the domain name. See audienceManager Server and audienceManagerServerSecure.
