fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User<p><span><strong class="command">named-checkzone</strong></span>
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User checks the syntax and integrity of a zone file. It performs the
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User same checks as <span><strong class="command">named</strong></span> does when loading a
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User checking zone files before configuring them into a name server.

fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User <span><strong class="command">named-compilezone</strong></span> is similar to
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User zone contents to a specified file in a specified format.
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User Additionally, it applies stricter check levels by default,
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User since the dump output will be used as an actual zone file
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User loaded by <span><strong class="command">named</strong></span>.
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User When manually specified otherwise, the check levels must at
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User least be as strict as those specified in the
fae13836a33b474a6aa2c147df8334f5b1ffae45Tinderbox User <span><strong class="command">named</strong></span> configuration file.

by release 9.9.0 or higher. The default is 1.

Specify the style of the dumped zone file.
Possible styles are <span><strong class="command">"full"</strong></span> (default)
and <span><strong class="command">"relative"</strong></span>.
The full format is most suitable for processing
automatically by a separate script.
On the other hand, the relative format is more
human-readable and is thus suitable for editing by hand.
For <span><strong class="command">named-checkzone</strong></span>
this does not cause any effects unless it dumps the zone
contents.
It also does not have any meaning if the output format
is not text.

Specify whether to check for non-terminal wildcards.
Non-terminal wildcards are almost always the result of a
