Setting Up the Data Files

All the data files used by the DNS daemon in.named are written in standard resource record format. Each line of a file is a record, called a resource record (RR). Each DNS data file must contain certain resource records.

The most commonly used types of resource records are listed in Table 5–6. They are usually entered in the order shown in Table 5–6, but that is not a requirement.

In the sample files included in the following sections, @ indicates the current zone or origin and lines that begin with a semicolon (;) are comments.
