The Cisco Umbrella Virtual Appliances and roaming clients use a technology called DNSCrypt to embed the unique device identifiers into each DNS request.

Here's how it works:

1. DNSCrypt: This is a protocol that adds encryption to DNS traffic, enhancing security. In the context of Cisco Umbrella, it's also used to embed unique identifiers into DNS requests.

2. Embedding Identifiers: When a device makes a DNS request, the Umbrella roaming client or Virtual Appliance uses DNSCrypt to embed a unique identifier for that device into the request. This identifier is used by Cisco Umbrella to apply the appropriate policies for that device.

3. Policy Enforcement: When the DNS request reaches the Cisco Umbrella servers, the identifier is extracted and used to enforce the correct policies for that device. This allows for granular, device-specific control of network access and security.

So, DNSCrypt is the technology used by Cisco Umbrella to embed unique device identifiers into each DNS request.
