0f081398cf0eef8cc7c66a535d450110a92dc8aefielding is a multiple/pipelined query version of <command>dig</command>:
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding instead of waiting for a response after sending each query,
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding it begins by sending all queries. Responses are displayed in
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding the order in which they are received, not in the order the
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding corresponding queries were sent.

0f081398cf0eef8cc7c66a535d450110a92dc8aefielding The <arg choice="req" rep="norepeat">@server</arg> option is a mandatory global
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding option. It is the name or IP address of the name server to query.
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding (Unlike <command>dig</command>, this value is not retrieved from
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding <filename>/etc/resolv.conf</filename>.) It can be an IPv4 address
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding in dotted-decimal notation, an IPv6 address in colon-delimited
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding notation, or a hostname. When the supplied
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding <parameter>server</parameter> argument is a hostname,
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding <command>mdig</command> resolves that name before querying
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding the name server.

0f081398cf0eef8cc7c66a535d450110a92dc8aefielding provides a number of query options which affect
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding the way in which lookups are made and the results displayed. Some of
6db54801798f6021bb464de7b3fdcc9dc3150f7bdgaudet these set or reset flag bits in the query header, some determine which
032b8a34c3911bbc5ad5385ca40af65af273bff9wrowe sections of the answer get printed, and others determine the timeout
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding and retry strategies.

0f081398cf0eef8cc7c66a535d450110a92dc8aefielding option. These may be preceded by the string <literal>no</literal>
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding to negate the meaning of that keyword. Other keywords assign
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding values to options like the timeout interval. They have the

Reverse lookups &mdash; mapping addresses to names &mdash; are

<parameter>addr</parameter> is an IPv4
address in dotted-decimal notation, or a colon-delimited IPv6 address.
<command>mdig</command> automatically performs a lookup for a
query name like <literal>11.12.13.10.in-addr.arpa</literal> and
sets the query type and class to PTR and IN respectively.

<listitem>
<para>
Set [do not set] the AD (authentic data) bit in the
query. This requests the server to return whether
all of the answer and authority sections have all
been validated as secure according to the security
policy of the server. AD=1 indicates that all records
have been validated as secure and the answer is not
from a OPT-OUT range. AD=0 indicate that some part
of the answer was insecure or not validated. This
bit is set by default.

<para>
Set the UDP message buffer size advertised using EDNS0
to <parameter>B</parameter> bytes. The maximum and
minimum sizes of this buffer are 65535 and 0 respectively.
Values outside this range are rounded up or down
appropriately. Values other than zero will cause a
EDNS query to be sent.

<term><option>+[no]edns[=#]</option></term>
<listitem>
<para>
Specify the EDNS version to query with. Valid values
are 0 to 255. Setting the EDNS version will cause
a EDNS query to be sent. <option>+noedns</option>
clears the remembered EDNS version. EDNS is set to
0 by default.
</para>

</varlistentry>
<varlistentry>
<term><option>+[no]ednsflags[=#]</option></term>
<listitem>
<para>
Set the must-be-zero EDNS flags bits (Z bits) to the
specified value. Decimal, hex and octal encodings are
accepted. Setting a named flag (e.g. DO) will silently be
ignored. By default, no Z bits are set.

<term><option>+retry=T</option></term>
<listitem>
<para>

specified IP address or network prefix.
</para>
<para>
<command>mdig +subnet=0.0.0.0/0</command>, or simply
<command>mdig +subnet=0</command> for short, sends an EDNS
client-subnet option with an empty address and a source
prefix-length of zero, which signals a resolver that
the client's address information must
<emphasis>not</emphasis> be used when resolving
this query.
</para>

<varlistentry>
<term><option>+timeout=T</option></term>
<listitem>
<para>
Sets the timeout for a query to
<parameter>T</parameter> seconds. The default
timeout is 5 seconds for UDP transport and 10 for TCP.
An attempt to set <parameter>T</parameter> to less
than 1 will result
in a query timeout of 1 second being applied.

<term><option>+tries=T</option></term>
<listitem>
<para>
Sets the number of times to try UDP queries to server
