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 

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.
