RFC 9953: DNS over the Constrained Application Protocol (DoC)

Le protocole #CoAP est un protocole léger, conçu pour les objets connectés. Ce #RFC décrit comment faire du #DNS au-dessus de CoAP. Si votre brosse à dents a besoin de faire du DNS, c'est ce RFC qu'il faut lire.

Blog Stéphane Bortzmeyer: RFC 9953: DNS over the Constrained Application Protocol (DoC)

@bortzmeyer moi j’ai toujours pas compris pourquoi ma brosse à dents doit pouvoir accéder à Internet. Y’a des gens qui complète leur profil Strava avec leur ratio « dents à la minutes » ?

@joel @bortzmeyer [Excusez-moi, je ne parle pas français, so please bare with me replying in English] Well, it's not just tooth brushes... Farmers monitor their fields over LoRa or similar technologies, Industry 4.0 is also in that area, and much more. Tooth brushes and fridges are just an easily graspable thing for the general population to communicate the IoT (though I prefer thermostats as an example, everyone loves a pre-heated flat 😜 ).

@miri64 still I’m puzzled whether we should put IT connectivity everywhere. Don’t get me wrong, I love putting Shelly Plugs everywhere in the house and monitor and manage those via HomeAssistant. But my bathing room heater, my fish tanks lights and my LED strip work as good with an old disconnected mechanical outlet timer. Even if I have to change time twice a year.

@joel Even Home Assistant uses mDNS for the discovery of your devices, which currently is unencrypted. Though not all puzzle pieces are in place yet, DoC could allow for a secure mDNS using GroupOSCORE in the future.
