The configuration file is located in this file:

/etc/named.conf

The zone file name is based on the name of the zone. For example, the zone file “example.com” is located in this file:

/var/named/example.com.zone

See “Configuring BIND Using the Command Line” on page 37 for more information.

Step 3: Configure basic DNS settings

See “Managing DNS Service” on page 21 for more information.

Step 4: Create a DNS Zone

Use Server Admin to set up DNS zones. See “Managing Zones” on page 22 for instructions. After adding a master zone, Server Admin automatically creates an NS record with the same name as the Source of Authority (SOA).

Step 5: Add Address and additional records to the zone.

Use Server Admin to add additional records to your Zone. Create an Address record for every computer or device (printer, file server, etc.) that has a static IP address and needs a name. When you create an A record, you have the option to specify the creation of a reverse lookup record and it’s corresponding zone. See “Managing Records” on page 25 for instructions.

Step 6: Set up a mail exchange (MX) record (optional)

If you provide mail service over the Internet, you need to set up an MX record for your server. See “Setting Up MX Records” on page 33 for more information.

Step 7: Configure the reverse lookup zone (optional)

For each zone that you create, Mac OS X Server creates a reverse lookup zone. Reverse lookup zones translate IP addresses to domain names, rather than normal lookups which translate domain names to IP addresses. If you have not specified reverse lookup records when initially creating your A records, you might need to configure your reverse lookup zone after its creation.

Step 8: Start DNS service

Mac OS X Server includes a simple interface for starting and stopping DNS service.

See “Starting and Stopping DNS Service” on page 21 for more information.
