  36 <a name="id2543672"></a><h2>DESCRIPTION</h2>
  37 <p><span><strong class="command">named-checkzone</strong></span>
  38       checks the syntax and integrity of a zone file.  It performs the
  39       same checks as <span><strong class="command">named</strong></span> does when loading a
  40       zone.  This makes <span><strong class="command">named-checkzone</strong></span> useful for
  41       checking zone files before configuring them into a name server.
  42     </p>
  43 <p>
  44         <span><strong class="command">named-compilezone</strong></span> is similar to
  45         <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
  46         zone contents to a specified file in a specified format.
  47         Additionally, it applies stricter check levels by default,
  48         since the dump output will be used as an actual zone file
  49         loaded by <span><strong class="command">named</strong></span>.
  50         When manually specified otherwise, the check levels must at
  51         least be as strict as those specified in the
  52         <span><strong class="command">named</strong></span> configuration file.

  87               <span><strong class="command">"full"</strong></span> (default),

  95               refer to A or AAAA record (both in-zone and out-of-zone
  96               hostnames).  Mode <span><strong class="command">"local"</strong></span> only
  97               checks MX records which refer to in-zone hostnames.

 101               refer to A or AAAA record (both in-zone and out-of-zone
 102               hostnames).  Mode <span><strong class="command">"local"</strong></span> only

 107               records refer to A or AAAA record (both in-zone and out-of-zone
 108               hostnames).  It also checks that glue address records
 109               in the zone match those advertised by the child.
 110               Mode <span><strong class="command">"local"</strong></span> only checks NS records which
 111               refer to in-zone hostnames or that some required glue exists,
 112               that is when the nameserver is in a child zone.

 117               checks but are otherwise the same as <span><strong class="command">"full"</strong></span>
 118               and <span><strong class="command">"local"</strong></span> respectively.
 119           </p>

 184             and <span><strong class="command">"relative"</strong></span>.
 185             The full format is most suitable for processing
 186             automatically by a separate script.
 187             On the other hand, the relative format is more
 188             human-readable and is thus suitable for editing by hand.

 190             this does not cause any effects unless it dumps the zone
