hello.

What is the DoC?
Shane Kerr - 2026-05-21 14:10:44
DoT == DNS over TLS DoH == DNS over HTTPS DoQ == DNS over QUIC DoC == ???
Greg Choules - 2026-05-21 14:11:12
I thought I heard "COPE"?
Michael Richardson - 2026-05-21 14:11:21
Good question. I don't know either.... COAP.
Michael Richardson - 2026-05-21 14:12:04
RFC 9953 DNS over CoAP (DoC)
Michael Richardson - 2026-05-21 14:12:19
wow. I didn't notice it was xx53.
Michael Richardson - 2026-05-21 14:13:34
https://www.rfc-editor.org/info/rfc9953/ is now beautiful.

Shane Kerr - 2026-05-21 14:14:55
Cool! Now I have to learn about DoC. 😆
Michael Richardson - 2026-05-21 14:14:56
Jim: while residential battery powered IoT devices still abound, but both connected fridges and OT plant motor controllers often have lots of power. Like 3-phase 30Amp :-)
Michael Richardson - 2026-05-21 14:15:36
DoC is very much targeted at the energy harvesting battery powered device....
Shane Kerr - 2026-05-21 14:16:54
Hm... DoC requires DTLS, it seems?
Michael Richardson - 2026-05-21 14:17:17
"*can* be protected by (D)TLS"
Shane Kerr - 2026-05-21 14:18:24
Ah. "The use of DoC without confidentiality and integrity protection is NOT RECOMMENDED." Indeed, it is optional.
Michael Richardson - 2026-05-21 14:48:40
sounds like RFC8520, MUD.
Michael Richardson - 2026-05-21 14:51:25
glad they didn't re-invent that!
Michael Richardson - 2026-05-21 15:28:35
I wonder if I fell off the ML.
