Feature Description

The Device ID in EDNS0 Records allows each enterprise with a customized domain-blocking functionality 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/configured with the Device ID in the EDNS0 packet.

For more information, refer to the Device ID in EDNS0 Records chapter.
