Feature Description
The Device ID in EDNS0 offers each enterprise with a customized domain blocking through Umbrella. To enable this functionality:
-
The UPF must reformat a subscriber DNS request into an EDNS0 request, and.
-
The UPF must include an Umbrella “Device ID” in the EDNS0 packet so that the Umbrella DNS resolver can use the Device ID to apply the domain filter associated or configured with the Device ID in the EDNS0 packet.
Presently, the Session Management Function (SMF) receives the domain filtering policy ID from PCRF/PCF. The SMF passes the domain filtering policy ID to the User Plane Function (UPF) in the Subscriber Parameters. The UPF uses the domain filtering policy ID to apply domain filtering functionality to the subscriber.
