DNS-based Service Discovery (DNS-SD) over Multicast DNS (mDNS) is widely used today for discovery and resolution of services and names on a local link, but there are use cases to extend DNS-SD/mDNS to enable service discovery beyond the local link. This document provides a problem statement and a list of requirements for scalable DNS-SD.
