Abstract: Provided are computer-implemented methods and systems for repurposing a Domain Name System (DNS) as a business data transport layer. An example method for repurposing the DNS as a business data transport layer includes collecting business telemetry data associated with an Internet of Things (IoT) device. The business telemetry data is collected by at least one telemetry sensor installed on the IoT device. The method further includes generating, by the IoT device, an Extended DNS (EDNS) packet. The EDNS packet includes a DNS address associated with a DNS server of a business data center associated with the IoT device manufacturer or supporting server and the business telemetry data stored in at least one extension field of the EDNS packet. The EDNS packet is then routed to the DNS server associated with the business data center of the IoT device manufacturer or supporting server as part of the DNS request.
