It performs DNS lookups and -displays the answers that are returned from the name server(s) that -were queried. Most DNS administrators use <span><strong class="command">dig</strong></span> to -troubleshoot DNS problems because of its flexibility, ease of use and -clarity of output. Other lookup tools tend to have less functionality -than <span><strong class="command">dig</strong></span>. -</p> -<p> -Although <span><strong class="command">dig</strong></span> 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 <code class="option">-h</code> option is given. -Unlike earlier versions, the BIND9 implementation of -<span><strong class="command">dig</strong></span> allows multiple lookups to be issued from the -command line. -</p> -<p> -Unless it is told to query a specific name server, -<span><strong class="command">dig</strong></span> will try each of the servers listed in -<code class="filename">/etc/resolv.conf</code>. -</p> -<p> -When no command line arguments or options are given, will perform an -NS query for "." (the root). -</p> -<p> -It is possible to set per-user defaults for <span><strong class="command">dig</strong></span> via -<code class="filename">${HOME}/.digrc</code>. This file is read and any options in it -are applied before the command line arguments. -</p> -</div> -<div class="refsect1" lang="en"> -<a name="id2526035"></a><h2>SIMPLE USAGE</h2> -<p> -A typical invocation of <span><strong class="command">dig</strong></span> looks like: -</p> -<pre class="programlisting"> dig @server name type </pre> -<p> where: - -</p> -<div class="variablelist"><dl> -<dt><span class="term"><code class="constant">server</code></span></dt> -<dd><p> -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 -<em class="parameter"><code>server</code></em> argument is a hostname, -<span><strong class="command">dig</strong></span> resolves that name before querying that name -server. If no <em class="parameter"><code>server</code></em> argument is provided, -<span><strong class="command">dig</strong></span> consults <code class="filename">/etc/resolv.conf</code> -and queries the name servers listed there. The reply from the name -server that responds is displayed. -</p></dd> -<dt><span class="term"><code class="constant">name</code></span></dt> -<dd><p> -is the name of the resource record that is to be looked up. -</p></dd> -<dt><span class="term"><code class="constant">type</code></span></dt> -<dd><p> -indicates what type of query is required — -ANY, A, MX, SIG, etc. -<em class="parameter"><code>type</code></em> can be any valid query type. If no -<em class="parameter"><code>type</code></em> argument is supplied, -<span><strong class="command">dig</strong></span> will perform a lookup for an A record. -</p></dd> -</dl></div> -<p> -</p> -</div> -<div class="refsect1" lang="en"> -<a name="id2526114"></a><h2>OPTIONS</h2> -<p> -The <code class="option">-b</code> option sets the source IP address of the query -to <em class="parameter"><code>address</code></em>. This must be a valid address on -one of the host's network interfaces or "0.0.0.0" or "::". An optional port -may be specified by appending "#<port>" -</p> -<p> -The default query class (IN for internet) is overridden by the -<code class="option">-c</code> option. <em class="parameter"><code>class</code></em> is any valid -class, such as HS for Hesiod records or CH for CHAOSNET records. -</p> -<p> -The <code class="option">-f</code> option makes <span><strong class="command">dig </strong></span> operate -in batch mode by reading a list of lookup requests to process from the -file <em class="parameter"><code>filename</code></em>. The file contains a number of -queries, one per line. Each entry in the file should be organised in -the same way they would be presented as queries to -<span><strong class="command">dig</strong></span> using the command-line interface. -</p> -<p> -If a non-standard port number is to be queried, the -<code class="option">-p</code> option is used. <em class="parameter"><code>port#</code></em> is -the port number that <span><strong class="command">dig</strong></span> will send its queries -instead of the standard DNS port number 53. This option would be used -to test a name server that has been configured to listen for queries -on a non-standard port number. -</p> -<p> -The <code class="option">-4</code> option forces <span><strong class="command">dig</strong></span> to only -use IPv4 query transport. The <code class="option">-6</code> option forces -<span><strong class="command">dig</strong></span> to only use IPv6 query transport. -</p> -<p> -The <code class="option">-t</code> option sets the query type to -<em class="parameter"><code>type</code></em>. It can be any valid query type which is -supported in BIND9. The default query type "A", unless the -<code class="option">-x</code> option is supplied to indicate a reverse lookup. -A zone transfer can be requested by specifying a type of AXFR. When -an incremental zone transfer (IXFR) is required, -<em class="parameter"><code>type</code></em> is set to <code class="literal">ixfr=N</code>. -The incremental zone transfer will contain the changes made to the zone -since the serial number in the zone's SOA record was -<em class="parameter"><code>N</code></em>. -</p> -<p> -Reverse lookups - mapping addresses to names - are simplified by the -<code class="option">-x</code> option. <em class="parameter"><code>addr</code></em> is an IPv4 -address in dotted-decimal notation, or a colon-delimited IPv6 address. -When this option is used, there is no need to provide the -<em class="parameter"><code>name</code></em>, <em class="parameter"><code>class</code></em> and -<em class="parameter"><code>type</code></em> arguments. <span><strong class="command">dig</strong></span> -automatically performs a lookup for a name like -<code class="literal">11.12.13.10.in-addr.arpa</code> 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. -To use the older RFC1886 method using the IP6.INT domain -specify the <code class="option">-i</code> option. Bit string labels (RFC2874) -are now experimental and are not attempted. -</p> -<p> -To sign the DNS queries sent by <span><strong class="command">dig</strong></span> and their -responses using transaction signatures (TSIG), specify a TSIG key file -using the <code class="option">-k</code> option. You can also specify the TSIG -key itself on the command line using the <code class="option">-y</code> option; -<em class="parameter"><code>name</code></em> is the name of the TSIG key and -<em class="parameter"><code>key</code></em> is the actual key. The key is a base-64 -encoded string, typically generated by <span class="citerefentry"><span class="refentrytitle">dnssec-keygen</span>(8)</span>. - -Caution should be taken when using the <code class="option">-y</code> option on -multi-user systems as the key can be visible in the output from -<span class="citerefentry"><span class="refentrytitle">ps</span>(1 -)</span> or in the shell's history file. When -using TSIG authentication with <span><strong class="command">dig</strong></span>, the name -server that is queried needs to know the key and algorithm that is -being used. In BIND, this is done by providing appropriate -<span><strong class="command">key</strong></span> and <span><strong class="command">server</strong></span> statements in -<code class="filename">named.conf</code>. -</p> -</div> -<div class="refsect1" lang="en"> -<a name="id2526365"></a><h2>QUERY OPTIONS</h2> -<p> -<span><strong class="command">dig</strong></span> 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. -</p> -<p> -Each query option is identified by a keyword preceded by a plus sign -(<code class="literal">+</code>). Some keywords set or reset an option. These may be preceded -by the string <code class="literal">no</code> to negate the meaning of that keyword.
