12.3 About DNS Configuration Files

Domains are grouped into zones and zones are configured through the use of zone files. Zone files store information about domains in the DNS database. Each zone file contains directives and resource records. Optional directives apply settings to a zone or instruct a name server to perform certain tasks. Resource records specify zone parameters and define information about the systems (hosts) in a zone.
