12.3.3. Example Zone File
Seen individually, directives and resource records can be difficult to grasp. However, when placed together in a single file, they become easier to understand.
The following example shows a very basic zone file.
In this example, standard directives and
SOA
values are used. The authoritative nameservers are set as dns1.example.com
and dns2.example.com
, which have A
records that tie them to 10.0.1.2
and 10.0.1.3
, respectively.
The email servers configured with the
MX
records point to server1
and server2
via CNAME
records. Since the server1
and server2
names do not end in a trailing period (.
), the $ORIGIN
domain is placed after them, expanding them to server1.example.com
and server2.example.com
. Through the related A
resource records, their IP addresses can be determined.
FTP and Web services, available at the standard
ftp.example.com
and www.example.com
names, are pointed at the appropriate servers using CNAME
records.
