This document defines a protocol for exchanging DNS queries (OPCODE
0) over the Constrained Application Protocol (CoAP). These CoAP
messages can be protected by (D)TLS-Secured CoAP or Object Security
for Constrained RESTful Environments (OSCORE) to provide encrypted
DNS message exchange for constrained devices in the Internet of
Things (IoT).
This document is a product of the Constrained RESTful Environments Working
Group of the IETF.
This is now a Proposed Standard.
