Network Administration: BIND Zone Files
Each zone for which your DNS server is authoritative should have a zone file, named domain.zone and located in the /var/named directory. If you like to edit DNS records directly, you can create this file yourself. Or you can use the point-and-click interface of the Fedora BIND configuration tool to automatically create the file.
Here’s a typical zone file, named lowewriter.com.zone:
$TTL 86400 @ IN SOA ns207.pair.com. root.localhost ( 2 ; serial 28800 ; refresh 7200 ; retry 604800 ; expire 86400 ; ttl ) IN NS ns000.ns0.com. IN NS ns207.pair.com. @ IN MX 1 sasi.pair.com. www IN A 184.108.40.206
