+mdig \- DNS pipelined lookup utility
+.SH SYNOPSIS
+.sp
+\fBmdig\fP \fI\%{@server\fP} [\fB\-f\fP filename] [\fB\-h\fP] [\fB\-v\fP] [ [\fB\-4\fP] | [\fB\-6\fP] ] [\fB\-m\fP] [\fB\-b\fP address] [\fB\-p\fP port#] [\fB\-c\fP class] [\fB\-t\fP type] [\fB\-i\fP] [\fB\-x\fP addr] [plusopt...]
+.sp
+\fBmdig\fP {\fB\-h\fP}
+.sp
+\fBmdig\fP [@server] {global\-opt...} { {local\-opt...} {query} ...}
+.SH DESCRIPTION
+.sp
+\fBmdig\fP is a multiple/pipelined query version of \fI\%dig\fP: instead of
+waiting for a response after sending each query, it begins by sending
+all queries. Responses are displayed in the order in which they are
+received, not in the order the corresponding queries were sent.
+.sp
+\fBmdig\fP options are a subset of the \fI\%dig\fP options, and are divided
+into \(dqanywhere options,\(dq which can occur anywhere, \(dqglobal options,\(dq which
+must occur before the query name (or they are ignored with a warning),
+and \(dqlocal options,\(dq which apply to the next query on the command line.
+.sp
+The \fB@server\fP option is a mandatory global option. It is the name or IP
+address of the name server to query. (Unlike \fI\%dig\fP, this value is not
+retrieved from \fB/etc/resolv.conf\fP\&.) It can be an IPv4 address in
+dotted\-decimal notation, an IPv6 address in colon\-delimited notation, or
+a hostname. When the supplied \fBserver\fP argument is a hostname,
+\fBmdig\fP resolves that name before querying the name server.
+.sp
+\fBmdig\fP 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.
+.sp
+Each query option is identified by a keyword preceded by a plus sign
+(\fB+\fP). Some keywords set or reset an option. These may be preceded by
+the string \fBno\fP to negate the meaning of that keyword. Other keywords
+assign values to options like the timeout interval. They have the form
+\fB+keyword=value\fP\&.
+.SH ANYWHERE OPTIONS
+.INDENT 0.0
+.TP
+.B \-f
+This option makes \fBmdig\fP operate in batch mode by reading a list
+of lookup requests to process from the file \fBfilename\fP\&. 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 \fBmdig\fP using the command\-line interface.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-h
+This option causes \fBmdig\fP to print detailed help information, with the full list
+of options, and exit.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-v
+This option causes \fBmdig\fP to print the version number and exit.
+.UNINDENT
+.SH GLOBAL OPTIONS
+.INDENT 0.0
+.TP
+.B \-4
+This option forces \fBmdig\fP to only use IPv4 query transport.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-6
+This option forces \fBmdig\fP to only use IPv6 query transport.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-b address
+This option sets the source IP address of the query to
+\fBaddress\fP\&. This must be a valid address on one of the host\(aqs network
+interfaces or \(dq0.0.0.0\(dq or \(dq::\(dq. An optional port may be specified by
+appending \(dq#<port>\(dq
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-m
+This option enables memory usage debugging.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-p port#
+This option is used when a non\-standard port number is to be
+queried. \fBport#\fP is the port number that \fBmdig\fP sends its
+queries to, instead of the standard DNS port number 53. This option is
+used to test a name server that has been configured to listen for
+queries on a non\-standard port number.
+.UNINDENT
+.sp
+The global query options are:
+.INDENT 0.0
+.TP
+.B +additional, +noadditional

+default is to not display malformed answers.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +burst
+This option delays queries until the start of the next second.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +cl, +nocl
+This option displays [or does not display] the CLASS when printing the record.

+print comments.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +continue, +nocontinue
+This option toggles continuation on errors (e.g. timeouts).
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +crypto, +nocrypto
+This option toggles the display of cryptographic fields in DNSSEC records. The
+contents of these fields are unnecessary to debug most DNSSEC
+validation failures and removing them makes it easier to see the
+common failures. The default is to display the fields. When omitted,
+they are replaced by the string \(dq[omitted]\(dq; in the DNSKEY case, the
+key ID is displayed as the replacement, e.g., \fB[ key id = value ]\fP\&.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +dscp=value
+This option formerly set the DSCP value used when sending a query.
+It is now obsolete, and has no effect.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +multiline, +nomultiline
+This option toggles printing of records, like the SOA records, in a verbose multi\-line format
+with human\-readable comments. The default is to print each record on
+a single line, to facilitate machine parsing of the \fBmdig\fP output.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +question, +noquestion
+This option prints [or does not print] the question section of a query when an answer
+is returned. The default is to print the question section as a
+comment.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +rrcomments, +norrcomments
+This option toggles the display of per\-record comments in the output (for example,
+human\-readable key information about DNSKEY records). The default is
+not to print record comments unless multiline mode is active.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +short, +noshort
+This option provides [or does not provide] a terse answer. The default is to print the answer in a
+verbose form.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +split=W
+This option splits long hex\- or base64\-formatted fields in resource records into
+chunks of \fBW\fP characters (where \fBW\fP is rounded up to the nearest
+multiple of 4). \fB+nosplit\fP or \fB+split=0\fP causes fields not to be
+split. The default is 56 characters, or 44 characters when
+multiline mode is active.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +tcp, +notcp
+This option uses [or does not use] TCP when querying name servers. The default behavior
+is to use UDP.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +ttlid, +nottlid
+This option displays [or does not display] the TTL when printing the record.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +ttlunits, +nottlunits
+This option displays [or does not display] the TTL in friendly human\-readable time
+units of \(dqs\(dq, \(dqm\(dq, \(dqh\(dq, \(dqd\(dq, and \(dqw\(dq, representing seconds, minutes,
+hours, days, and weeks. This implies +ttlid.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +vc, +novc
+This option uses [or does not use] TCP when querying name servers. This alternate
+syntax to \fI\%+tcp\fP is provided for backwards compatibility. The
+\fBvc\fP stands for \(dqvirtual circuit\(dq.
+.UNINDENT
+.SH LOCAL OPTIONS
+.INDENT 0.0
+.TP
+.B \-c class
+This option sets the query class to \fBclass\fP\&. It can be any valid
+query class which is supported in BIND 9. The default query class is
+\(dqIN\(dq.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-t type
+This option sets the query type to \fBtype\fP\&. It can be any valid
+query type which is supported in BIND 9. The default query type is \(dqA\(dq,
+unless the \fI\%\-x\fP option is supplied to indicate a reverse lookup with
+the \(dqPTR\(dq query type.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-x addr
+Reverse lookups \- mapping addresses to names \- are simplified by
+this option. \fBaddr\fP is an IPv4 address in dotted\-decimal
+notation, or a colon\-delimited IPv6 address. \fBmdig\fP automatically
+performs a lookup for a query name like \fB11.12.13.10.in\-addr.arpa\fP 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.
+.UNINDENT
+.sp
+The local query options are:
+.INDENT 0.0
+.TP
+.B +aaflag, +noaaflag
+This is a synonym for \fI\%+aaonly\fP, \fI\%+noaaonly\fP\&.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +aaonly, +noaaonly
+This sets the \fBaa\fP flag in the query.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +adflag, +noadflag
+This sets [or does 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
+indicates that some part of the answer was insecure or not validated.
+This bit is set by default.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +bufsize=B
+This sets the UDP message buffer size advertised using EDNS0 to \fBB\fP
+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 cause a EDNS query to be
+sent.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +cdflag, +nocdflag
+This sets [or does not set] the CD (checking disabled) bit in the query. This
+requests the server to not perform DNSSEC validation of responses.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +cookie=####, +nocookie
+This sends [or does not send] a COOKIE EDNS option, with an optional value. Replaying a COOKIE
+from a previous response allows the server to identify a previous
+client. The default is \fB+nocookie\fP\&.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +dnssec, +nodnssec
+This requests that DNSSEC records be sent by setting the DNSSEC OK (DO) bit in
+the OPT record in the additional section of the query.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +edns[=#], +noedns
+This specifies [or does not specify] the EDNS version to query with. Valid values are 0 to 255.
+Setting the EDNS version causes an EDNS query to be sent.
+\fB+noedns\fP clears the remembered EDNS version. EDNS is set to 0 by
+default.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +ednsflags[=#], +noednsflags
+This sets the must\-be\-zero EDNS flag bits (Z bits) to the specified value.
+Decimal, hex, and octal encodings are accepted. Setting a named flag
+(e.g. DO) is silently ignored. By default, no Z bits are set.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +ednsopt[=code[:value]], +noednsopt
+This specifies [or does not specify] an EDNS option with code point \fBcode\fP and an optional payload
+of \fBvalue\fP as a hexadecimal string. \fB+noednsopt\fP clears the EDNS
+options to be sent.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +expire, +noexpire
+This toggles sending of an EDNS Expire option.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +nsid, +nonsid
+This toggles inclusion of an EDNS name server ID request when sending a query.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +recurse, +norecurse
+This toggles the setting of the RD (recursion desired) bit in the query.
+This bit is set by default, which means \fBmdig\fP normally sends
+recursive queries.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +retry=T
+This sets the number of times to retry UDP queries to server to \fBT\fP
+instead of the default, 2. Unlike \fI\%+tries\fP, this does not include
+the initial query.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +subnet=addr[/prefix\-length], +nosubnet
+This sends [or does not send] an EDNS Client Subnet option with the specified IP
+address or network prefix.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \fBmdig +subnet=0.0.0.0/0\fP, or simply \fBmdig +subnet=0\fP
+This sends an EDNS client\-subnet option with an empty address and a source
+prefix\-length of zero, which signals a resolver that the client\(aqs
+address information must \fInot\fP be used when resolving this query.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +timeout=T
+This sets the timeout for a query to \fBT\fP seconds. The default timeout is
+5 seconds for UDP transport and 10 for TCP. An attempt to set \fBT\fP
+to less than 1 results in a query timeout of 1 second being
+applied.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +tries=T
+This sets the number of times to try UDP queries to server to \fBT\fP
+instead of the default, 3. If \fBT\fP is less than or equal to zero,
+the number of tries is silently rounded up to 1.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +udptimeout=T
+This sets the timeout between UDP query retries to \fBT\fP\&.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +unknownformat, +nounknownformat
+This prints [or does not print] all RDATA in unknown RR\-type presentation format (see \fI\%RFC 3597\fP).
+The default is to print RDATA for known types in the type\(aqs
+presentation format.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +yaml, +noyaml
+This toggles printing of the responses in a detailed YAML format.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B +zflag, +nozflag
+This sets [or does not set] the last unassigned DNS header flag in a DNS query.
+This flag is off by default.
