DNS-Based Service Discovery (DNS-SD) Privacy and Security Requirements, September 2020
Discuss this RFC: Send questions or comments to firstname.lastname@example.org
DNS-SD (DNS-based Service Discovery) normally discloses information about devices offering and requesting services. This information includes hostnames, network parameters, and possibly a further description of the corresponding service instance. Especially when mobile devices engage in DNS-based Service Discovery at a public hotspot, serious privacy problems arise. We analyze the requirements of a privacy-respecting discovery service.
