+
+ <para><command>Nslookup</command>
+ is a program to query Internet domain name servers. <command>Nslookup</command>
+ has two modes: interactive and non-interactive. Interactive mode allows
+ the user to query name servers for information about various hosts and
+ domains or to print a list of hosts in a domain. Non-interactive mode
+ is
+ used to print just the name and requested information for a host or
+ domain.
+ </para>
+ </refsection>
+
+ <refsection><info><title>ARGUMENTS</title></info>
+
+ <para>
+ Interactive mode is entered in the following cases:
+ <orderedlist numeration="loweralpha" inheritnum="ignore" continuation="restarts">
+ <listitem>
+ <para>
+ when no arguments are given (the default name server will be used)
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ when the first argument is a hyphen (-) and the second argument is
+ the host name or Internet address of a name server.
+ </para>
+ </listitem>
+ </orderedlist>
+ </para>
+
+ <para>
+ Non-interactive mode is used when the name or Internet address of the
+ host to be looked up is given as the first argument. The optional second
+ argument specifies the host name or address of a name server.
+ </para>
+
+ <para>
+ Options can also be specified on the command line if they precede the
+ arguments and are prefixed with a hyphen. For example, to
+ change the default query type to host information, and the initial
+ timeout to 10 seconds, type:
+ <!-- <informalexample> produces bad nroff. -->
+ <programlisting>
+nslookup -query=hinfo -timeout=10
+</programlisting>
+ <!-- </informalexample> -->
+ </para>
+ <para>
+ The <option>-version</option> option causes
+ <command>nslookup</command> to print the version
+ number and immediately exits.
+ </para>
