+
+ <p><span class="command"><strong>named-checkzone</strong></span>
+ checks the syntax and integrity of a zone file. It performs the
+ same checks as <span class="command"><strong>named</strong></span> does when loading a
+ zone. This makes <span class="command"><strong>named-checkzone</strong></span> useful for
+ checking zone files before configuring them into a name server.
+ </p>
+ <p>
+ <span class="command"><strong>named-compilezone</strong></span> is similar to
+ <span class="command"><strong>named-checkzone</strong></span>, but it always dumps the
+ zone contents to a specified file in a specified format.
+ Additionally, it applies stricter check levels by default,
+ since the dump output will be used as an actual zone file
+ loaded by <span class="command"><strong>named</strong></span>.
+ When manually specified otherwise, the check levels must at
+ least be as strict as those specified in the
+ <span class="command"><strong>named</strong></span> configuration file.
+ </p>

+ Mode <span class="command"><strong>"local"</strong></span> only checks NS records which
