7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont is a multiple/pipelined query version of <command>dig</command>:
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont instead of waiting for a response after sending each query,
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont it begins by sending all queries. Responses are displayed in
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont the order in which they are received, not in the order the
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont corresponding queries were sent.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont <command>mdig</command> options are a subset of the
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont <command>dig</command> options, and are divided into "anywhere
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont options" which can occur anywhere, "global options" which must
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont occur before the query name (or they are ignored with a warning),
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont and "local options" which apply to the next query on the command
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt The <arg choice="req" rep="norepeat">@server</arg> option is a mandatory global
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont option. It is the name or IP address of the name server to query.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont (Unlike <command>dig</command>, this value is not retrieved from
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont <filename>/etc/resolv.conf</filename>.) It can be an IPv4 address
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont in dotted-decimal notation, an IPv6 address in colon-delimited
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont notation, or a hostname. When the supplied
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont <parameter>server</parameter> argument is a hostname,
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont <command>mdig</command> resolves that name before querying
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont the name server.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont provides a number of query options which affect
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont the way in which lookups are made and the results displayed. Some of
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont these set or reset flag bits in the query header, some determine which
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont sections of the answer get printed, and others determine the timeout
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont and retry strategies.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont Each query option is identified by a keyword preceded by a plus
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont sign (<literal>+</literal>). Some keywords set or reset an
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont option. These may be preceded by the string <literal>no</literal>
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont to negate the meaning of that keyword. Other keywords assign
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont values to options like the timeout interval. They have the

7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont The <option>-f</option> option makes <command>mdig</command>
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont operate in batch mode by reading a list of lookup requests to
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont process from the file <parameter>filename</parameter>. The file
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont contains a number of queries, one per line. Each entry in the
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont file should be organized in the same way they would be presented
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont as queries to <command>mdig</command> using the command-line interface.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont The <option>-h</option> causes <command>mdig</command> to
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont print the detailed help with the full list of options and exit.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont The <option>-v</option> causes <command>mdig</command> to
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont print the version number and exit.

7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont The <option>-4</option> option forces <command>mdig</command> to
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont only use IPv4 query transport.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont The <option>-6</option> option forces <command>mdig</command> to

7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont The <option>-b</option> option sets the source IP address of the
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont query to <parameter>address</parameter>. This must be a valid
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont address on one of the host's network interfaces or "0.0.0.0" or
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont "::". An optional port may be specified by appending

832f5803f69f4548ba3777f8b5741768bbbf5f75Mark Andrews The <option>-m</option> option enables memory usage debugging.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont The <option>-p</option> option is used when a non-standard port
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont number is to be queried.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont <parameter>port#</parameter> is the port number
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont that <command>mdig</command> will send its queries instead of
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont the standard DNS port number 53. This option would be used to
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont test a name server that has been configured to listen for
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont queries on a non-standard port number.

7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont which is supported in BIND 9. The default query type is "A",

7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont sets the query type and class to PTR and IN respectively.
7768b049c0b39662baca604ec32b32c6480f8dc6Francis Dupont By default, IPv6 addresses are looked up using nibble format
