Managing Records

Each zone contains a number of records. These records are requested when a client computer needs to translate a domain name (like www.example.com) to an IP number. Web browsers, email clients, and other network applications rely on a zone’s records to contact the appropriate server.

The master zone’s records will be queried by others across the Internet so they can connect to your network services. There are several kinds of DNS records. The records which are available for configuration by Server Admin’s user interface are:

•Address (A): Stores the IP address associated with a domain name.

•Canonical Name (CNAME): Stores the “real name” of a server when given a “nickname” or alias. For example, mail.apple.com might have a canonical name of MailSrv473.apple.com.

•Mail Exchanger (MX): Stores the domain name of the computer that is used for email in a zone.
