-
-    <para><command>dig</command> 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 addresses
-      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
-      domain 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.

-
-
-    <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.

-      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>.
-      Keywords may be abbreviated, provided the abbreviation is
-      unambiguous; for example, <literal>+cd</literal> is equivalent

-    <para>
-      The BIND 9 implementation of <command>dig </command>
-      supports
-      specifying multiple queries on the command line (in addition to
-      supporting the <option>-f</option> batch file option).  Each of those
-      queries can be supplied with its own set of flags, options and query
-      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>.

-    <para><command>host</command>
-      is a simple utility for performing DNS lookups.
-      It is normally used to convert names to IP addresses and vice versa.
-      When no arguments or options are given,
-      <command>host</command>
-      prints a short summary of its command line arguments and options.
-    </para>
-
-    <para><parameter>name</parameter> is the domain name that is to be
-      looked
-      up.  It can also be a dotted-decimal IPv4 address or a colon-delimited
-      IPv6 address, in which case <command>host</command> will by
-      default
-      perform a reverse lookup for that address.
-      <parameter>server</parameter> is an optional argument which
-      is either
-      the name or IP address of the name server that <command>host</command>

-
-    <para><command>Nslookup</command>
-      is a program to query Internet domain name servers.  <command>Nslookup</command>
-      has two modes: interactive and non-interactive.  Interactive mode allows
-      the user to query name servers for information about various hosts and
-      domains or to print a list of hosts in a domain.  Non-interactive mode
-      is
-      used to print just the name and requested information for a host or
-      domain.
-    </para>

-
-    <para>
-      Interactive mode is entered in the following cases:
-      <orderedlist numeration="loweralpha" inheritnum="ignore" continuation="restarts">
-        <listitem>
-          <para>
-            when no arguments are given (the default name server will be used)
-          </para>
-        </listitem>
-        <listitem>
-          <para>
-            when the first argument is a hyphen (-) and the second argument is
-            the host name or Internet address of a name server.
-          </para>
-        </listitem>
-      </orderedlist>
-    </para>
-
-    <para>
-      Non-interactive mode is used when the name or Internet address of the
-      host to be looked up is given as the first argument. The optional second
-      argument specifies the host name or address of a name server.
-    </para>
-
-    <para>
-      Options can also be specified on the command line if they precede the
-      arguments and are prefixed with a hyphen.  For example, to
-      change the default query type to host information, and the initial
-      timeout to 10 seconds, type:
-      <!-- <informalexample> produces bad nroff. -->
-        <programlisting>
-nslookup -query=hinfo  -timeout=10
-</programlisting>
-      <!-- </informalexample> -->
-    </para>
-    <para>
-      The <option>-version</option> option causes
-      <command>nslookup</command> to print the version
-      number and immediately exits.

-          <para>
-            Look up information for host using the current default server or
-            using server, if specified.  If host is an Internet address and
-            the query type is A or PTR, the name of the host is returned.
-            If host is a name and does not have a trailing period, the
-            search list is used to qualify the name.

-  <refsection><info><title>DESCRIPTION</title></info>
-
-    <para>
-      The BIND 9 lightweight resolver library is a simple, name service
-      independent stub resolver library.  It provides hostname-to-address
-      and address-to-hostname lookup services to applications by
-      transmitting lookup requests to a resolver daemon
-      <command>lwresd</command>
-      running on the local host. The resolver daemon performs the
-      lookup using the DNS or possibly other name service protocols,
-      and returns the results to the application through the library.
-      The library and resolver daemon communicate using a simple
-      UDP-based protocol.
-    </para>
-  </refsection>
-
-  <refsection><info><title>OVERVIEW</title></info>
-
-    <para>
-      The lwresd library implements multiple name service APIs.
-      The standard
-      <function>gethostbyname()</function>,
-      <function>gethostbyaddr()</function>,
-      <function>gethostbyname_r()</function>,
-      <function>gethostbyaddr_r()</function>,
-      <function>getaddrinfo()</function>,
-      <function>getipnodebyname()</function>,
-      and
-      <function>getipnodebyaddr()</function>
-      functions are all supported.  To allow the lwres library to coexist
-      with system libraries that define functions of the same name,
-      the library defines these functions with names prefixed by
-      <literal>lwres_</literal>.
-      To define the standard names, applications must include the
-      header file
-      <filename>&lt;lwres/netdb.h&gt;</filename>
-      which contains macro definitions mapping the standard function names
-      into
-      <literal>lwres_</literal>
-      prefixed ones.  Operating system vendors who integrate the lwres
-      library into their base distributions should rename the functions
-      in the library proper so that the renaming macros are not needed.
-    </para>
-    <para>
-      The library also provides a native API consisting of the functions
-      <function>lwres_getaddrsbyname()</function>
-      and
-      <function>lwres_getnamebyaddr()</function>.
-      These may be called by applications that require more detailed
-      control over the lookup process than the standard functions
-      provide.
-    </para>
-    <para>
-      In addition to these name service independent address lookup
-      functions, the library implements a new, experimental API
-      for looking up arbitrary DNS resource records, using the
-      <function>lwres_getaddrsbyname()</function>
-      function.
-    </para>
-    <para>
-      Finally, there is a low-level API for converting lookup
-      requests and responses to and from raw lwres protocol packets.
-      This API can be used by clients requiring nonblocking operation,
-      and is also used when implementing the server side of the lwres
-      protocol, for example in the
-      <command>lwresd</command>
-      resolver daemon.  The use of this low-level API in clients
-      and servers is outlined in the following sections.
-    </para>
-  </refsection>
-  <refsection><info><title>CLIENT-SIDE LOW-LEVEL API CALL FLOW</title></info>
-
-    <para>
-      When a client program wishes to make an lwres request using the
-      native low-level API, it typically performs the following
-      sequence of actions.
-    </para>
-    <para>
-      (1) Allocate or use an existing <type>lwres_packet_t</type>,
-      called <varname>pkt</varname> below.
-    </para>
-    <para>
-      (2) Set <varname remap="structfield">pkt.recvlength</varname> to the maximum length
-      we will accept.
-      This is done so the receiver of our packets knows how large our receive
-      buffer is.  The "default" is a constant in
-      <filename>lwres.h</filename>: <constant>LWRES_RECVLENGTH = 4096</constant>.
-    </para>
-    <para>
-      (3) Set <varname remap="structfield">pkt.serial</varname>
-      to a unique serial number.  This value is echoed
-      back to the application by the remote server.
-    </para>
-    <para>
-      (4) Set <varname remap="structfield">pkt.pktflags</varname>.  Usually this is set to
-      0.
-    </para>
-    <para>
-      (5) Set <varname remap="structfield">pkt.result</varname> to 0.
-    </para>
-    <para>
-      (6) Call <function>lwres_*request_render()</function>,
-      or marshall in the data using the primitives
-      such as <function>lwres_packet_render()</function>
-      and storing the packet data.
-    </para>
-    <para>
-      (7) Transmit the resulting buffer.
-    </para>
-    <para>
-      (8) Call <function>lwres_*response_parse()</function>
-      to parse any packets received.
-    </para>
-    <para>
-      (9) Verify that the opcode and serial match a request, and process the
-      packet specific information contained in the body.
-    </para>
-  </refsection>
-  <refsection><info><title>SERVER-SIDE LOW-LEVEL API CALL FLOW</title></info>
-
-    <para>
-      When implementing the server side of the lightweight resolver
-      protocol using the lwres library, a sequence of actions like the
-      following is typically involved in processing each request packet.
-    </para>
-    <para>
-      Note that the same <type>lwres_packet_t</type> is used
-      in both the <function>_parse()</function> and <function>_render()</function> calls,
-      with only a few modifications made
-      to the packet header's contents between uses.  This method is
-      recommended
-      as it keeps the serial, opcode, and other fields correct.
-    </para>
-    <para>
-      (1) When a packet is received, call <function>lwres_*request_parse()</function> to
-      unmarshall it.  This returns a <type>lwres_packet_t</type> (also called <varname>pkt</varname>, below)
-      as well as a data specific type, such as <type>lwres_gabnrequest_t</type>.
-    </para>
-    <para>
-      (2) Process the request in the data specific type.
-    </para>
-    <para>
-      (3) Set the <varname remap="structfield">pkt.result</varname>,
-      <varname remap="structfield">pkt.recvlength</varname> as above.  All other fields
-      can
-      be left untouched since they were filled in by the <function>*_parse()</function> call
-      above.  If using <function>lwres_*response_render()</function>,
-      <varname remap="structfield">pkt.pktflags</varname> will be set up
-      properly.  Otherwise, the <constant>LWRES_LWPACKETFLAG_RESPONSE</constant> bit should be
-      set.
-    </para>
-    <para>
-      (4) Call the data specific rendering function, such as
-      <function>lwres_gabnresponse_render()</function>.
-    </para>
-    <para>
-      (5) Send the resulting packet to the client.

-    <para>
-      These functions provide bounds checked access to a region of memory
-      where data is being read or written.
-      They are based on, and similar to, the
-      <literal>isc_buffer_</literal>
-      functions in the ISC library.
-    </para>
-    <para>
-      A buffer is a region of memory, together with a set of related
-      subregions.
-      The <emphasis>used region</emphasis> and the
-      <emphasis>available</emphasis> region are disjoint, and
-      their union is the buffer's region.
-      The used region extends from the beginning of the buffer region to the
-      last used byte.
-      The available region extends from one byte greater than the last used
-      byte to the end of the  buffer's region.
-      The size of the used region can be changed using various
-      buffer commands.
-      Initially, the used region is empty.
-    </para>
-    <para>
-      The used region is further subdivided into two disjoint regions: the
-      <emphasis>consumed region</emphasis> and the <emphasis>remaining region</emphasis>.
-      The union of these two regions is the used region.
-      The consumed region extends from the beginning of the used region to
-      the byte before the <emphasis>current</emphasis> offset (if any).
-      The <emphasis>remaining</emphasis> region the current pointer to the end
-      of the used
-      region.
-      The size of the consumed region can be changed using various
-      buffer commands.
-      Initially, the consumed region is empty.
-    </para>
-    <para>
-      The <emphasis>active region</emphasis> is an (optional) subregion of the
-      remaining
-      region.
-      It extends from the current offset to an offset in the
-      remaining region.
-      Initially, the active region is empty.
-      If the current offset advances beyond the chosen offset,
-      the active region will also be empty.

-    </para>
-    <para><function>lwres_buffer_invalidate()</function>
-      marks the buffer <parameter>*b</parameter>

-      checks for buffer overflow and

-      A buffer is re-initialised by

-    <para><function>lwres_context_create()</function>
-      creates a <type>lwres_context_t</type> structure for use in
-      lightweight resolver operations.  It holds a socket and other
-      data needed for communicating with a resolver daemon.  The new
-      <type>lwres_context_t</type> is returned through
-      <parameter>contextp</parameter>, a pointer to a
-      <type>lwres_context_t</type> pointer.  This
-      <type>lwres_context_t</type> pointer must initially be NULL, and
-      is modified to point to the newly created
-      <type>lwres_context_t</type>.
-    </para>
-    <para>
-      When the lightweight resolver needs to perform dynamic memory
-      allocation, it will call
-      <parameter>malloc_function</parameter>
-      to allocate memory and
-      <parameter>free_function</parameter>
-      to free it.  If
-      <parameter>malloc_function</parameter>
-      and
-      <parameter>free_function</parameter>
-      are NULL, memory is allocated using
-      <citerefentry>
-        <refentrytitle>malloc</refentrytitle><manvolnum>3</manvolnum>

-        <refentrytitle>free</refentrytitle><manvolnum>3</manvolnum>
-      </citerefentry>.
-
-      It is not permitted to have a NULL
-      <parameter>malloc_function</parameter> and a non-NULL
-      <parameter>free_function</parameter> or vice versa.
-      <parameter>arg</parameter> is passed as the first parameter to
-      the memory allocation functions.  If
-      <parameter>malloc_function</parameter> and
-      <parameter>free_function</parameter> are NULL,
-      <parameter>arg</parameter> is unused and should be passed as
-      NULL.
-    </para>
-
-    <para>
-      Once memory for the structure has been allocated,

-
-    <para><function>lwres_context_destroy()</function>
-      destroys a <type>lwres_context_t</type>, closing its socket.
-      <parameter>contextp</parameter> is a pointer to a pointer to the
-      context that is to be destroyed.  The pointer will be set to
-      NULL when the context has been destroyed.
-    </para>
-
-    <para>
-      The context holds a serial number that is used to identify
-      resolver request packets and associate responses with the
-      corresponding requests.  This serial number is controlled using
-      <function>lwres_context_initserial()</function> and
-      <function>lwres_context_nextserial()</function>.
-      <function>lwres_context_initserial()</function> sets the serial
-      number for context <parameter>*ctx</parameter> to
-      <parameter>serial</parameter>.
-      <function>lwres_context_nextserial()</function> increments the
-      serial number and returns the previous value.
-    </para>
-
-    <para>
-      Memory for a lightweight resolver context is allocated and freed
-      using <function>lwres_context_allocmem()</function> and
-      <function>lwres_context_freemem()</function>.  These use
-      whatever allocations were defined when the context was created
-      with <function>lwres_context_create()</function>.
-      <function>lwres_context_allocmem()</function> allocates
-      <parameter>len</parameter> bytes of memory and if successful
-      returns a pointer to the allocated storage.
-      <function>lwres_context_freemem()</function> frees
-      <parameter>len</parameter> bytes of space starting at location
-      <parameter>mem</parameter>.
-    </para>
-
-    <para><function>lwres_context_sendrecv()</function>
-      performs I/O for the context <parameter>ctx</parameter>.  Data
-      are read and written from the context's socket.  It writes data

-      lightweight resolver query packet &mdash; and waits for a reply
-      which is copied to the receive buffer at
-      <parameter>recvbase</parameter>.  The number of bytes that were

-      There are four main functions for the getaddrbyname opcode.
-      One render function converts a getaddrbyname request structure &mdash;
-      <type>lwres_gabnrequest_t</type> &mdash;
-      to the lightweight resolver's canonical format.
-      It is complemented by a parse function that converts a packet in this
-      canonical format to a getaddrbyname request structure.
-      Another render function converts the getaddrbyname response structure
-      &mdash; <type>lwres_gabnresponse_t</type> &mdash;
-      to the canonical format.
-      This is complemented by a parse function which converts a packet in
-      canonical format to a getaddrbyname response structure.

-
-      The function is the lightweight resolver's implementation of

-      <parameter>hostname</parameter> and
-      <parameter>servname</parameter> are pointers to null-terminated

-
-      <parameter>hostname</parameter> is either a host name or a
-      numeric host address string: a dotted decimal IPv4 address or an
-      IPv6 address.  <parameter>servname</parameter> is either a

-      <filename>/etc/services</filename>.
-    </para>
-
-    <para><parameter>hints</parameter>

-      This structure can be used to provide hints concerning the type of

-      that the caller supports or wishes to use.
-      The caller can supply the following structure elements in
-      <parameter>*hints</parameter>:

-    <para>
-      These are low-level routines for creating and parsing
-      lightweight resolver address-to-name lookup request and
-      response messages.
-    </para>
-    <para>
-      There are four main functions for the getnamebyaddr opcode.
-      One render function converts a getnamebyaddr request structure &mdash;
-      <type>lwres_gnbarequest_t</type> &mdash;
-      to the lightweight resolver's canonical format.
-      It is complemented by a parse function that converts a packet in this
-      canonical format to a getnamebyaddr request structure.
-      Another render function converts the getnamebyaddr response structure
-      &mdash;
-      <type>lwres_gnbaresponse_t</type>
-      to the canonical format.
-      This is complemented by a parse function which converts a packet in
-      canonical format to a getnamebyaddr response structure.
-    </para>
-    <para>
-      These structures are defined in
-      <filename>lwres/lwres.h</filename>.
-      They are shown below.

-    <para>
-      These are low-level routines for creating and parsing
-      lightweight resolver no-op request and response messages.
-    </para>
-    <para>
-      The no-op message is analogous to a <command>ping</command>
-      packet:
-      a packet is sent to the resolver daemon and is simply echoed back.
-      The opcode is intended to allow a client to determine if the server is
-      operational or not.
-    </para>
-    <para>
-      There are four main functions for the no-op opcode.
-      One render function converts a no-op request structure &mdash;
-      <type>lwres_nooprequest_t</type> &mdash;
-      to the lightweight resolver's canonical format.
-      It is complemented by a parse function that converts a packet in this
-      canonical format to a no-op request structure.
-      Another render function converts the no-op response structure &mdash;
-      <type>lwres_noopresponse_t</type>
-      to the canonical format.
-      This is complemented by a parse function which converts a packet in
-      canonical format to a no-op response structure.
-    </para>
-    <para>
-      These structures are defined in
-      <filename>lwres/lwres.h</filename>.
-
-      They are shown below.
-    </para>
-    <para><programlisting>

-    </para>
-    <para>
-      Although the structures have different types, they are identical.
-      This is because the no-op opcode simply echos whatever data was sent:
-      the response is therefore identical to the request.
-    </para>
-
-    <para><function>lwres_nooprequest_render()</function>
-      uses resolver context <parameter>ctx</parameter> to convert

-      is initialised and transferred to buffer
-      <parameter>b</parameter>.  The contents of
-      <parameter>*req</parameter> are then appended to the buffer in
-      canonical format.
-      <function>lwres_noopresponse_render()</function> performs the
-      same task, except it converts a no-op response structure
-      <type>lwres_noopresponse_t</type> to the lightweight resolver's

-    <para><function>lwres_nooprequest_parse()</function>

-      <parameter>b</parameter> provides space to be used for storing
-      this structure.  When the function succeeds, the resulting
-      <type>lwres_nooprequest_t</type> is made available through
-      <parameter>*structp</parameter>.
-      <function>lwres_noopresponse_parse()</function> offers the same

-      except it yields a <type>lwres_noopresponse_t</type> structure.

-    <para><function>lwres_string_parse()</function>
-      retrieves a DNS-encoded string starting the current pointer of
-      lightweight resolver buffer <parameter>b</parameter>: i.e.
-      <constant>b-&gt;current</constant>.  When the function returns,
-      the address of the first byte of the encoded string is returned
-      via <parameter>*c</parameter> and the length of that string is
-      given by <parameter>*len</parameter>.  The buffer's current
-      pointer is advanced to point at the character following the
-      string length, the encoded string, and the trailing
-      <type>NULL</type> character.
-    </para>
-
-    <para><function>lwres_addr_parse()</function>
-      extracts an address from the buffer <parameter>b</parameter>.
-      The buffer's current pointer <constant>b-&gt;current</constant>
-      is presumed to point at an encoded address: the address preceded
-      by a 32-bit protocol family identifier and a 16-bit length
-      field.  The encoded address is copied to
-      <constant>addr-&gt;address</constant> and
-      <constant>addr-&gt;length</constant> indicates the size in bytes
-      of the address that was copied.
-      <constant>b-&gt;current</constant> is advanced to point at the
-      next byte of available data in the buffer following the encoded
-      address.

-    <para>
-      The lightweight resolver uses
-      <function>lwres_getaddrsbyname()</function> to perform
-      forward lookups.
-      Hostname <parameter>name</parameter> is looked up using the
-      resolver
-      context <parameter>ctx</parameter> for memory allocation.
-      <parameter>addrtypes</parameter> is a bitmask indicating
-      which type of
-      addresses are to be looked up.  Current values for this bitmask are
-      <type>LWRES_ADDRTYPE_V4</type> for IPv4 addresses and
-      <type>LWRES_ADDRTYPE_V6</type> for IPv6 addresses.  Results of the
-      lookup are returned in <parameter>*structp</parameter>.
-    </para>
-
-    <para><function>lwres_getnamebyaddr()</function>
-      performs reverse lookups.  Resolver context
-      <parameter>ctx</parameter> is used for memory allocation.  The
-      address type is indicated by <parameter>addrtype</parameter>:
-      <type>LWRES_ADDRTYPE_V4</type> or
-      <type>LWRES_ADDRTYPE_V6</type>.  The address to be looked up is
-      given by <parameter>addr</parameter> and its length is
-      <parameter>addrlen</parameter> bytes.  The result of the
-      function call is made available through
-      <parameter>*structp</parameter>.
