Query using DNS

Service Directory supports DNS queries for the following record types:

• A/AAAA/SRV records for a service or an endpoint
• SOA/NS records for the private zone origin

For a detailed explanation of these record types, see List of DNS record types.

A/AAAA queries must observe the following format:

SERVICE_NAME.ZONE_DOMAIN_NAME

Optionally:

ENDPOINT_NAME.SERVICE_NAME.ZONE_DOMAIN_NAME

SRV queries must observe the following format:

_SERVICE_NAME._tcp.SERVICE_NAME.ZONE_DOMAIN_NAME

Note: SERVICE_NAME appears twice in the query name and the first label is preceded by a literal underscore character.

Optionally:

_SERVICE_NAME._tcp.ENDPOINT_NAME.SERVICE_NAME.ZONE_DOMAIN_NAME

All services and endpoints in Service Directory default to having their service name as the symbolic service and a protocol of tcp.
