 Abstract
 
    The Service Registration Protocol for DNS-Based Service Discovery
    uses the standard DNS Update mechanism to enable DNS-Based Service
    Discovery using only unicast packets.  This makes it possible to
    deploy DNS Service Discovery without multicast, which greatly
    improves scalability and improves performance on networks where
    multicast service is not an optimal choice, particularly 802.11
    (Wi-Fi) and 802.15.4 (IoT) networks.  DNS-SD Service registration
