Manage Apex Domains In OS X

OS X Server supports running a traditional bind implementation of DNS. You can define a record for most any name, including,,, etc. You can use this to redirect subdomains. In this example, we’ll create an A Record to point to without breaking other subdomains. To get started, let’s use the DNS service in the Server app to create The reason for this is that OS X will then create a zone file for If we created instead, then OS X would automatically create, which would break the other subdomains. To do so, open Server app and click on the DNS Service. Then click on the plus sign to create a new record.

To then change, we’d edit the zone file stored at /Library/Server/named/ This file will look like this when you first open it: 10800 IN SOA ( 2014092301 ; serial 3600 ; refresh (1 hour) 900 ; retry (15 minutes) 1209600 ; expire (2 weeks) 86400 ; minimum (1 day) ) 10800 IN NS 10800 IN A We’ll add an a record for 10801 IN A Now, to change the apex record, you’d just replace the name you’ve been using with an @: @ 10801 IN A Good luck!
