<p>
<span><strong class="command">named-checkzone</strong></span> checks the syntax and integrity of
a zone file. It performs the same checks as <span><strong class="command">named</strong></span>
does when loading a zone. This makes
<span><strong class="command">named-checkzone</strong></span> useful for checking zone
files before configuring them into a name server.
