 EDNS extends the DNS protocol, enabling larger UDP packets to carry additional data. In AdGuard DNS, it allows passing the DeviceID in plain DNS using an extra parameter.
 
-DeviceID, an eight-digit hexadecimal identifier (e.g., `1a2b3c4d`), helps link DNS requests to specific devices. For encrypted DNS, this ID is part of the domain (e.g., `1a2b3c4d.d.adguard-dns.com`). For unencrypted DNS, EDNS is required to localize this identifier.

+The `dig` command is merely an example, you can use any DNS software with an ability to add EDNS options to perform this action.
