Administrator Commands and Files dig(8)
+[no]ignore Ignore [do not ignore] truncation in UDP responses instead of
retrying with TCP. By default, TCP retries are performed.
+domain=somename
Set the search list to contain the single domain somename,asif
specified in a domain directive in the /etc/resolv.conf file, and
enable search list processing as if the +search option were
given.
+[no]search Use [do not use] the search list defined by the searchlist or
domain directive in the /etc/resolv.conf file (if any). The search
list is not used by default.
+[no]defname Deprecated; treated as a synonym for +[no]search.
+[no]aaonly | +[no]aaflag
Set [do not set] the aa flag in the query.
+[no]adflag Set [do not set] the AD (authentic data) bit in the query. The AD
bit currently has a standard meaning only in responses, not in
queries, but the ability to set the bit in the query is provided for
completeness.
+[no]cdflag Set [do not set] the CD (checking disabled) bit in the query.
This requests the server to not perform DNSSEC validation of
responses.
+[no]cl Display [do not display] the class when printing the record.
+[no]ttlid Display [do not display] the TTL when printing the record.
+[no]recurse Set [do not set ] the RD (recursion desired) bit in the query. This
bit is set by default, which means dig normally sends recursive
queries. Recursion is automatically disabled when the
+nssearch or +trace query options are used.
+[no]nssearch Search for [do not search for] authoritative name servers for the
zone containing the name being looked up and display the SOA
record that each name server has for the zone.
+[no]trace Set [do not set] tracing of the delegation path from the root name
servers for the name being looked up. Tracing is disabled by
default.
When tracing is enabled, dig makes iterative queries to resolve
the name being looked up. dig follows referrals from the root
servers, showing the answer from each server that was used to
resolve the lookup.
+[no]cmd Set [do not set] printing of the initial comment in the output,
which identifies the version of dig and the query options that
have been applied. This comment is printed by default.
+[no]short Provide [do not provide] a terse answer. The default is to print
the answer in a verbose form.
