A caching server stores recent requests so that it can respond without forwarding the request to another DNS server.<br /> <br /> == Configuration ==<br /> <br /> When looking a the default named.conf file, you will see that it is set up to create a caching only DNS server.<br /> <br /> The options directive contains several directives including:<br /> <br /> * Listen-on port / Listen-on-v6 port - this specifies the TCP/IP port. To extend this to the local network a network address of the network card needs to be added.<br /> <br /> &lt;syntaxhighlight&gt;<br /> listen-on port 53 {127.0.0.1; 192.168.122.50}<br /> &lt;/syntaxhighlight&gt;<br /> <br /> * The directory directive specifies the location of the DNS data files. If the bind-chroot package is installed these files are hard linked to /var/named/chroot<br /> <br /> * dump-file specifies the cache location and output location from rndc flush<br /> <br /> * statistics-file specifies the cache location and output location from rndc stats<br /> <br /> * memstatistics-file specifies the location of the memory usage statistics<br /> <br /> * allow-query lists the ips allowed to get data from the server<br /> <br /> * dnssec-* specifies the security options</div>
