12.1.3. BIND as a Nameserver
BIND performs name resolution services through the /usr/sbin/named daemon. BIND also includes an administration utility called /usr/sbin/rndc. More information about rndc can be found in Section 12.4, “Using rndc”.
BIND stores its configuration files in the following locations:
/etc/named.conf — The configuration file for the named daemon.
/var/named/ directory — The named working directory which stores zone, statistic, and cache files.
The next few sections review the BIND configuration files in more detail.
