+Description
+~~~~~~~~~~~
+
+``named-checkzone`` checks the syntax and integrity of a zone file. It
+performs the same checks as ``named`` does when loading a zone. This
+makes ``named-checkzone`` useful for checking zone files before
+configuring them into a name server.
+
+Options
+~~~~~~~
+
+``-d``
+   This option enables debugging.
+
+``-h``
+   This option prints the usage summary and exits.
+
+``-q``
+   This option sets quiet mode, which only sets an exit code to indicate
+   successful or failed completion.
+
+``-v``
+   This option prints the version of the ``named-checkzone`` program and exits.
+
+``-j``
+   When loading a zone file, this option tells ``named`` to read the journal if it exists. The journal
+   file name is assumed to be the zone file name with the
+   string ``.jnl`` appended.
+
+``-J filename``
+   When loading the zone file, this option tells ``named`` to read the journal from the given file, if
+   it exists. This implies ``-j``.
+
+``-c class``
+   This option specifies the class of the zone. If not specified, ``IN`` is assumed.
+
+``-i mode``
+   This option performs post-load zone integrity checks. Possible modes are
+   ``full`` (the default), ``full-sibling``, ``local``,
+   ``local-sibling``, and ``none``.
+
+   Mode ``full`` checks that MX records refer to A or AAAA records
+   (both in-zone and out-of-zone hostnames). Mode ``local`` only
+   checks MX records which refer to in-zone hostnames.
+
+   Mode ``full`` checks that SRV records refer to A or AAAA records
+   (both in-zone and out-of-zone hostnames). Mode ``local`` only
+   checks SRV records which refer to in-zone hostnames.
+
+   Mode ``full`` checks that delegation NS records refer to A or AAAA
+   records (both in-zone and out-of-zone hostnames). It also checks that
+   glue address records in the zone match those advertised by the child.
+   Mode ``local`` only checks NS records which refer to in-zone
+   hostnames or verifies that some required glue exists, i.e., when the
+   name server is in a child zone.
+
+   Modes ``full-sibling`` and ``local-sibling`` disable sibling glue
+   checks, but are otherwise the same as ``full`` and ``local``,
+   respectively.
+
+   Mode ``none`` disables the checks.
+
+``-f format``
+   This option specifies the format of the zone file. Possible formats are
+   ``text`` (the default), ``raw``, and ``map``.
+
+``-F format``
+   This option specifies the format of the output file specified. For
+   ``named-checkzone``, this does not have any effect unless it dumps
+   the zone contents.
+
+   Possible formats are ``text`` (the default), which is the standard
+   textual representation of the zone, and ``map``, ``raw``, and ``raw=N``, which
+   store the zone in a binary format for rapid loading by ``named``.
+   ``raw=N`` specifies the format version of the raw zone file: if ``N`` is
+   0, the raw file can be read by any version of ``named``; if N is 1, the
+   file can only be read by release 9.9.0 or higher. The default is 1.
+
+``-k mode``
+   This option performs ``check-names`` checks with the specified failure mode.
+   Possible modes are ``fail``, ``warn`` (the default), and ``ignore``.
+
+``-l ttl``
+   This option sets a maximum permissible TTL for the input file. Any record with a
+   TTL higher than this value causes the zone to be rejected. This
+   is similar to using the ``max-zone-ttl`` option in ``named.conf``.
+
+``-L serial``
+   When compiling a zone to ``raw`` or ``map`` format, this option sets the "source
+   serial" value in the header to the specified serial number. This is
+   expected to be used primarily for testing purposes.
+
+``-m mode``
+   This option specifies whether MX records should be checked to see if they are
+   addresses. Possible modes are ``fail``, ``warn`` (the default), and
+   ``ignore``.
+
+``-M mode``
+   This option checks whether a MX record refers to a CNAME. Possible modes are
+   ``fail``, ``warn`` (the default), and ``ignore``.
+
+``-n mode``
+   This option specifies whether NS records should be checked to see if they are
+   addresses. Possible modes are ``fail``, ``warn`` (the default), and ``ignore``.
+
+``-o filename``
+   This option writes the zone output to ``filename``. If ``filename`` is ``-``, then
+   the zone output is written to standard output.
+
+``-r mode``
+   This option checks for records that are treated as different by DNSSEC but are
+   semantically equal in plain DNS. Possible modes are ``fail``,
+   ``warn`` (the default), and ``ignore``.
+
+``-s style``
+   This option specifies the style of the dumped zone file. Possible styles are
+   ``full`` (the default) and ``relative``. The ``full`` format is most
+   suitable for processing automatically by a separate script.
+   The relative format is more human-readable and is thus
+   suitable for editing by hand. This does not have any effect unless it dumps
+   the zone contents. It also does not have any meaning if the output format
+   is not text.
+
+``-S mode``
+   This option checks whether an SRV record refers to a CNAME. Possible modes are
+   ``fail``, ``warn`` (the default), and ``ignore``.
+
+``-t directory``
+   This option tells ``named`` to chroot to ``directory``, so that ``include`` directives in the
+   configuration file are processed as if run by a similarly chrooted
+   ``named``.
+
+``-T mode``
+   This option checks whether Sender Policy Framework (SPF) records exist and issues a
+   warning if an SPF-formatted TXT record is not also present. Possible
+   modes are ``warn`` (the default) and ``ignore``.
+
+``-w directory``
+   This option instructs ``named`` to chdir to ``directory``, so that relative filenames in master file
+   ``$INCLUDE`` directives work. This is similar to the directory clause in
+   ``named.conf``.
+
+``-D``
+   This option dumps the zone file in canonical format.
+
+``-W mode``
+   This option specifies whether to check for non-terminal wildcards. Non-terminal
+   wildcards are almost always the result of a failure to understand the
+   wildcard matching algorithm (:rfc:`4592`). Possible modes are ``warn``
+   (the default) and ``ignore``.
+
+``zonename``
+   This indicates the domain name of the zone being checked.
+
+``filename``
+   This is the name of the zone file.
+
+Return Values
+~~~~~~~~~~~~~
+
+``named-checkzone`` returns an exit status of 1 if errors were detected
+and 0 otherwise.
