Dedicated systems (usually embedded systems) with exactly one Server installed may not have a separate LDS. Such Servers shall become their own LDS or LDS-ME by implementing FindServers and GetEndpoints Services at the well-known address for an LDS. They should also announce themselves on the MulticastSubnet with a basic MulticastExtension. This requires a small subset of an mDNS Responder (see mDNS and Annex C) that announces the Server and responds to mDNS probes. The Server may not provide the caching and address resolution implemented by a full mDNS Responder.
