VISIBILITY CONTROL FOR DOMAIN NAME SYSTEM SERVICE DISCOVERY

Techniques are provided for performing domain name system (DNS) service discovery based on policy evaluations. In an embodiment, policy data is represented as DNS-SD records and is used to control visibility of services for service requesting devices. The policy data may describe policies for a particular type of a service or a particular service delivery unit. The visibility of service delivery units is determined through evaluations of the policies in policy data. In some embodiments, additional metadata may be retrieved to be used in the policy evaluations. In certain embodiments, based on the policy evaluations service data about only a subset of service delivery units available is returned to a service requesting device in response to a DNS-SD query.
