I have reviewed draft-ietf-dnssd-prireq-04. The document is informative and clear with a few editorial nits on section 4.1 through 4.3. I have reviewed from the IoT devices perspective and most likely for the consumer devices that might be present in the public network and are using shared network technologies (wireless or wired). The threat model are applicable to them. Section 3.1 describes implications for wearable and server related privacy issue. Perhaps a small paragraph might be added in this section or in the introduction calling out possible privacy and security threats on personal IoT devices in the public places ( that might act as a dns-sd client). At the same time, considering limited processing capabilities, battery saving concern considerations, privacy related extra processing of messages from the dns-sd server should not be mandated for the IoT devices. Depending on the device capabilities, the feature can be configurable and the user can turn on/off at their need; additionally some iot devices may not care about the privacy at all. So, a few additional lines on IoT implications for the threat model and yet flexibility of implementation of the dns-sd IOT client may be mentioned in the document to clarify the IoT devices in the shared wireless/wired medium.
