Use the Server app to create a service record. Service (SRV) records define services available on a domain. These records help computers with the location of a service on a domain.
In the DNS pane, click the Action pop-up menu , then choose Show All Records.
Click Add , then choose Add Service record from the pop-up menu.
Click the Zone pop-up menu, then choose a zone.
The service record is added to this zone.
In the Service Name field, enter the well-known name of the service.
Choose a service type from the Service Type pop-up menu.
If the service type for the service you’re providing isn’t listed, enter the name in the Service Type field. The name should use a syntax similar to _application protocol name._tcp | _udp.
In the Host Name field, enter the DNS name of the server that’s providing the service.
This is the fully qualified domain name of the service.
In the Port field, enter the port number for the service you’re providing.
For example, if you’re providing http service, use port 80.
In the Priority field, enter the priority number.
The priority number is used when multiple hosts are configured for the same service. The priority determines which host is tried first.
In the Weight field, enter a number.
The weight number is used as a relative weight for records with the same priority.
In the TXT field, enter additional information about the service.
This creates a TXT record for the service.
Click Create.
