-    <title>DESCRIPTION</title>
-    <para><command>dig</command>
-      (domain information groper) is a flexible tool
-      for interrogating DNS name servers.  It performs DNS lookups and
-      displays the answers that are returned from the name server(s) that
-      were queried.  Most DNS administrators use <command>dig</command> to
-      troubleshoot DNS problems because of its flexibility, ease of use and
-      clarity of output.  Other lookup tools tend to have less functionality
-      than <command>dig</command>.
-    </para>
-
-    <para>
-      Although <command>dig</command> is normally used with
-      command-line
-      arguments, it also has a batch mode of operation for reading lookup
-      requests from a file.  A brief summary of its command-line arguments
-      and options is printed when the <option>-h</option> option is given.
-      Unlike earlier versions, the BIND 9 implementation of
-      <command>dig</command> allows multiple lookups to be issued
-      from the
-      command line.
-    </para>
-
-    <para>
-      Unless it is told to query a specific name server,
-      <command>dig</command> will try each of the servers listed in
-      <filename>/etc/resolv.conf</filename>. If no usable server addreses
-      are found, <command>dig</command> will send the query to the local
-      host.
-    </para>
-
-    <para>
-      When no command line arguments or options are given,
-      <command>dig</command> will perform an NS query for "." (the root).
-    </para>
-
-    <para>
-      It is possible to set per-user defaults for <command>dig</command> via
-      <filename>${HOME}/.digrc</filename>.  This file is read and
-      any options in it
-      are applied before the command line arguments.
-    </para>
-
-    <para>
-      The IN and CH class names overlap with the IN and CH top level
-      domains names.  Either use the <option>-t</option> and
-      <option>-c</option> options to specify the type and class, 
-      use the <option>-q</option> the specify the domain name, or
-      use "IN." and "CH." when looking up these top level domains.

-    <title>SIMPLE USAGE</title>
-
-    <para>
-      A typical invocation of <command>dig</command> looks like:
-      <programlisting> dig @server name type </programlisting>
-      where:
-
-      <variablelist>
-
-        <varlistentry>
-          <term><constant>server</constant></term>
-          <listitem>
-            <para>
-              is the name or IP address of the name server to query.  This
-              can be an IPv4 address in dotted-decimal notation or an IPv6
-              address in colon-delimited notation.  When the supplied
-              <parameter>server</parameter> argument is a hostname,
-              <command>dig</command> resolves that name before querying
-              that name server.
-            </para>
-            <para>
-              If no <parameter>server</parameter> argument is
-              provided, <command>dig</command> consults
-              <filename>/etc/resolv.conf</filename>; if an
-              address is found there, it queries the name server at
-              that address. If either of the <option>-4</option> or
-              <option>-6</option> options are in use, then
-              only addresses for the corresponding transport
-              will be tried.  If no usable addresses are found,
-              <command>dig</command> will send the query to the
-              local host.  The reply from the name server that
-              responds is displayed.
-            </para>
-          </listitem>
-        </varlistentry>

-          <listitem>
-            <para>
-              indicates what type of query is required &mdash;
-              ANY, A, MX, SIG, etc.
-              <parameter>type</parameter> can be any valid query
-              type.  If no
-              <parameter>type</parameter> argument is supplied,
-              <command>dig</command> will perform a lookup for an
-              A record.

-    <title>OPTIONS</title>
-
-    <para>
-      The <option>-b</option> option sets the source IP address of the query
-      to <parameter>address</parameter>.  This must be a valid
-      address on
-      one of the host's network interfaces or "0.0.0.0" or "::".  An optional
-      port
-      may be specified by appending "#&lt;port&gt;"
-    </para>
-
-    <para>
-      The default query class (IN for internet) is overridden by the
-      <option>-c</option> option.  <parameter>class</parameter> is
-      any valid
-      class, such as HS for Hesiod records or CH for Chaosnet records.
-    </para>
-
-    <para>
-      The <option>-f</option> option makes <command>dig </command>
-      operate
-      in batch mode by reading a list of lookup requests to process from the
-      file <parameter>filename</parameter>.  The file contains a
-      number of
-      queries, one per line.  Each entry in the file should be organized in
-      the same way they would be presented as queries to
-      <command>dig</command> using the command-line interface.
-    </para>
-
-    <para>
-      The <option>-m</option> option enables memory usage debugging.
-      <!-- It enables ISC_MEM_DEBUGTRACE and ISC_MEM_DEBUGRECORD
-           documented in include/isc/mem.h -->
-    </para>
-
-    <para>
-      If a non-standard port number is to be queried, the
-      <option>-p</option> option is used.  <parameter>port#</parameter> is
-      the port number that <command>dig</command> will send its
-      queries
-      instead of the standard DNS port number 53.  This option would be used
-      to test a name server that has been configured to listen for queries
-      on a non-standard port number.
-    </para>
-
-    <para>
-      The <option>-4</option> option forces <command>dig</command>
-      to only
-      use IPv4 query transport.  The <option>-6</option> option forces
-      <command>dig</command> to only use IPv6 query transport.
-    </para>
-
-    <para>
-      The <option>-t</option> option sets the query type to
-      <parameter>type</parameter>.  It can be any valid query type
-      which is
-      supported in BIND 9.  The default query type is "A", unless the
-      <option>-x</option> option is supplied to indicate a reverse lookup.
-      A zone transfer can be requested by specifying a type of AXFR.  When
-      an incremental zone transfer (IXFR) is required,
-      <parameter>type</parameter> is set to <literal>ixfr=N</literal>.
-      The incremental zone transfer will contain the changes made to the zone
-      since the serial number in the zone's SOA record was
-      <parameter>N</parameter>.
-    </para>
-
-    <para>
-      The <option>-q</option> option sets the query name to 
-      <parameter>name</parameter>.  This useful do distinguish the
-      <parameter>name</parameter> from other arguments.
-    </para>
-
-    <para>
-      Reverse lookups &mdash; mapping addresses to names &mdash; are simplified by the
-      <option>-x</option> option.  <parameter>addr</parameter> is
-      an IPv4
-      address in dotted-decimal notation, or a colon-delimited IPv6 address.
-      When this option is used, there is no need to provide the
-      <parameter>name</parameter>, <parameter>class</parameter> and
-      <parameter>type</parameter> arguments.  <command>dig</command>
-      automatically performs a lookup for a name like
-      <literal>11.12.13.10.in-addr.arpa</literal> and sets the
-      query type and
-      class to PTR and IN respectively.  By default, IPv6 addresses are
-      looked up using nibble format under the IP6.ARPA domain.
-      To use the older RFC1886 method using the IP6.INT domain
-      specify the <option>-i</option> option.  Bit string labels (RFC2874)
-      are now experimental and are not attempted.
-    </para>
-
-    <para>
-      To sign the DNS queries sent by <command>dig</command> and
-      their
-      responses using transaction signatures (TSIG), specify a TSIG key file
-      using the <option>-k</option> option.  You can also specify the TSIG
-      key itself on the command line using the <option>-y</option> option;
-      <parameter>hmac</parameter> is the type of the TSIG, default HMAC-MD5,
-      <parameter>name</parameter> is the name of the TSIG key and
-      <parameter>key</parameter> is the actual key.  The key is a
-      base-64
-      encoded string, typically generated by
-      <citerefentry>
-        <refentrytitle>dnssec-keygen</refentrytitle><manvolnum>8</manvolnum>
-      </citerefentry>.
-
-      Caution should be taken when using the <option>-y</option> option on
-      multi-user systems as the key can be visible in the output from
-      <citerefentry>
-        <refentrytitle>ps</refentrytitle><manvolnum>1</manvolnum>
-      </citerefentry>
-      or in the shell's history file.  When
-      using TSIG authentication with <command>dig</command>, the name
-      server that is queried needs to know the key and algorithm that is
-      being used.  In BIND, this is done by providing appropriate
-      <command>key</command> and <command>server</command> statements in
-      <filename>named.conf</filename>.
-    </para>
-
-  </refsect1>
-
-  <refsect1>
-    <title>QUERY OPTIONS</title>
-
-    <para><command>dig</command>
-      provides a number of query options which affect
-      the way in which lookups are made and the results displayed.  Some of
-      these set or reset flag bits in the query header, some determine which
-      sections of the answer get printed, and others determine the timeout
-      and retry strategies.
-    </para>
-
-    <para>
-      Each query option is identified by a keyword preceded by a plus sign
-      (<literal>+</literal>).  Some keywords set or reset an
-      option.  These may be preceded
-      by the string <literal>no</literal> to negate the meaning of
-      that keyword.  Other
-      keywords assign values to options like the timeout interval.  They
-      have the form <option>+keyword=value</option>.
-      The query options are:
-
-      <variablelist>
-
-        <varlistentry>
-          <term><option>+[no]tcp</option></term>
-          <listitem>
-            <para>
-              Use [do not use] TCP when querying name servers.  The default
-              behavior is to use UDP unless an AXFR or IXFR query is
-              requested, in
-              which case a TCP connection is used.

-      options.
-    </para>
-
-    <para>
-      In this case, each <parameter>query</parameter> argument
-      represent an
-      individual query in the command-line syntax described above.  Each
-      consists of any of the standard options and flags, the name to be
-      looked up, an optional query type and class and any query options that
-      should be applied to that query.
-    </para>
-
-    <para>
-      A global set of query options, which should be applied to all queries,
-      can also be supplied.  These global query options must precede the
-      first tuple of name, class, type, options, flags, and query options
-      supplied on the command line.  Any global query options (except
-      the <option>+[no]cmd</option> option) can be
-      overridden by a query-specific set of query options.  For example:
-      <programlisting>
-dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr
-</programlisting>
-      shows how <command>dig</command> could be used from the
-      command line
-      to make three lookups: an ANY query for <literal>www.isc.org</literal>, a
-      reverse lookup of 127.0.0.1 and a query for the NS records of
-      <literal>isc.org</literal>.
-
-      A global query option of <parameter>+qr</parameter> is
-      applied, so
-      that <command>dig</command> shows the initial query it made
-      for each
-      lookup.  The final query has a local query option of
-      <parameter>+noqr</parameter> which means that <command>dig</command>
-      will not print the initial query when it looks up the NS records for
-      <literal>isc.org</literal>.

-    <title>IDN SUPPORT</title>
-    <para>
-      If <command>dig</command> has been built with IDN (internationalized
-      domain name) support, it can accept and display non-ASCII domain names.
-      <command>dig</command> appropriately converts character encoding of
-      domain name before sending a request to DNS server or displaying a
-      reply from the server.
-      If you'd like to turn off the IDN support for some reason, defines
-      the <envar>IDN_DISABLE</envar> environment variable.
-      The IDN support is disabled if the variable is set when 
-      <command>dig</command> runs.
