of backends. These backends can either be <link linkend="bindbackend">plain zonefiles</link> or be

<Para>
Prime examples of backends include relational databases, but also
loadbalancing and failover algorithms.
Before proceeding, it is advised to check the release notes for your PDNS version, as specified in the name of the distribution

+ Memory leaks in recursor fixed (c534, c572). In a test 800 million real life DNS packets have been sent to the
