Configuring a Caching-Only DNS Server

A caching-only DNS server is much simpler to set up and contains no zone data files, except for the root domain file—named.ca (which should be manually copied to the server during the initial configuration)—and the loopback reverse resolution file. The local server is always the master for this conceptual zone. A typical caching-only configuration file, /etc/named.conf, is shown here:

directory "/var/named";
cache                              named.ca
master      0.0.127.in-addr.arpa   named.local;

Note that the named.ca root domain file should be manually copied from the primary DNS server during the initial configuration.
