It can also be a dotted-decimal IPv4 address or a colon-delimited +IPv6 address, in which case <B +CLASS="COMMAND" +>host</B +> will by default +perform a reverse lookup for that address. +<VAR +CLASS="PARAMETER" +>server</VAR +> is an optional argument which is either +the name or IP address of the name server that <B +CLASS="COMMAND" +>host</B +> +should query instead of the server or servers listed in +<TT +CLASS="FILENAME" +>/etc/resolv.conf</TT +>.</P +><P +>The <VAR +CLASS="OPTION" +>-a</VAR +> (all) option is equivalent to setting the +<VAR +CLASS="OPTION" +>-v</VAR +> option and asking <B +CLASS="COMMAND" +>host</B +> to make +a query of type ANY.</P +><P +>When the <VAR +CLASS="OPTION" +>-C</VAR +> option is used, <B +CLASS="COMMAND" +>host</B +> +will attempt to display the SOA records for zone +<VAR +CLASS="PARAMETER" +>name</VAR +> from all the listed authoritative name +servers for that zone. The list of name servers is defined by the NS +records that are found for the zone.</P +><P +>The <VAR +CLASS="OPTION" +>-c</VAR +> option instructs to make a DNS query of class +<VAR +CLASS="PARAMETER" +>class</VAR +>. This can be used to lookup Hesiod or +Chaosnet class resource records. The default class is IN (Internet).</P +><P +>Verbose output is generated by <B +CLASS="COMMAND" +>host</B +> when the +<VAR +CLASS="OPTION" +>-d</VAR +> or <VAR +CLASS="OPTION" +>-v</VAR +> option is used. The two +options are equivalent. They have been provided for backwards +compatibility. In previous versions, the <VAR +CLASS="OPTION" +>-d</VAR +> option +switched on debugging traces and <VAR +CLASS="OPTION" +>-v</VAR +> enabled verbose +output.</P +><P +>List mode is selected by the <VAR +CLASS="OPTION" +>-l</VAR +> option. This makes +<B +CLASS="COMMAND" +>host</B +> perform a zone transfer for zone +<VAR +CLASS="PARAMETER" +>name</VAR +>. Transfer the zone printing out the NS, PTR +and address records (A/AAAA). If combined with <VAR +CLASS="OPTION" +>-a</VAR +> +all records will be printed. </P +><P +>The <VAR +CLASS="OPTION" +>-i</VAR +> +option specifies that reverse lookups of IPv6 addresses should +use the IP6.INT domain as defined in RFC1886. +The default is to use IP6.ARPA.</P +><P +>The <VAR +CLASS="OPTION" +>-N</VAR +> option sets the number of dots that have to be +in <VAR +CLASS="PARAMETER" +>name</VAR +> for it to be considered absolute. The +default value is that defined using the ndots statement in +<TT +CLASS="FILENAME" +>/etc/resolv.conf</TT +>, or 1 if no ndots statement is +present. Names with fewer dots are interpreted as relative names and +will be searched for in the domains listed in the <SPAN +CLASS="TYPE" +>search</SPAN +> +or <SPAN +CLASS="TYPE" +>domain</SPAN +> directive in +<TT +CLASS="FILENAME" +>/etc/resolv.conf</TT +>.</P +><P +>The number of UDP retries for a lookup can be changed with the +<VAR +CLASS="OPTION" +>-R</VAR +> option. <VAR +CLASS="PARAMETER" +>number</VAR +> indicates +how many times <B +CLASS="COMMAND" +>host</B +> will repeat a query that does +not get answered. The default number of retries is 1. If +<VAR +CLASS="PARAMETER" +>number</VAR +> is negative or zero, the number of +retries will default to 1.</P +><P +>Non-recursive queries can be made via the <VAR +CLASS="OPTION" +>-r</VAR +> option. +Setting this option clears the <SPAN +CLASS="TYPE" +>RD</SPAN +> — recursion +desired — bit in the query which <B +CLASS="COMMAND" +>host</B +> makes. +This should mean that the name server receiving the query will not +attempt to resolve <VAR +CLASS="PARAMETER" +>name</VAR +>. The +<VAR +CLASS="OPTION" +>-r</VAR +> option enables <B +CLASS="COMMAND" +>host</B +> to mimic +the behaviour of a name server by making non-recursive queries and +expecting to receive answers to those queries that are usually +referrals to other name servers.</P +><P +>By default <B +CLASS="COMMAND" +>host</B +> uses UDP when making queries. The +<VAR +CLASS="OPTION" +>-T</VAR +> option makes it use a TCP connection when querying +the name server. TCP will be automatically selected for queries that +require it, such as zone transfer (AXFR) requests.</P +><P +>The <VAR +CLASS="OPTION" +>-4</VAR +> option forces <B +CLASS="COMMAND" +>host</B +> to only +use IPv4 query transport. The <VAR +CLASS="OPTION" +>-6</VAR +> option forces +<B +CLASS="COMMAND" +>host</B +> to only use IPv6 query transport.</P +><P +>The <VAR +CLASS="OPTION" +>-t</VAR +> option is used to select the query type. +<VAR +CLASS="PARAMETER" +>type</VAR +> can be any recognised query type: CNAME, +NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified, +<B +CLASS="COMMAND" +>host</B +> automatically selects an appropriate query +type. By default it looks for A records, but if the +<VAR +CLASS="OPTION" +>-C</VAR +> option was given, queries will be made for SOA +records, and if <VAR +CLASS="PARAMETER" +>name</VAR +> is a dotted-decimal IPv4 +address or colon-delimited IPv6 address, <B +CLASS="COMMAND" +>host</B +> will +query for PTR records. If a query type of IXFR is chosen the starting +serial number can be specified by appending an equal followed by the +starting serial number (e.g. -t IXFR=12345678).</P +><P +>The time to wait for a reply can be controlled through the +<VAR +CLASS="OPTION" +>-W</VAR +> and <VAR +CLASS="OPTION" +>-w</VAR +> options. The +<VAR +CLASS="OPTION" +>-W</VAR +> option makes <B +CLASS="COMMAND" +>host</B +> wait for +<VAR +CLASS="PARAMETER" +>wait</VAR +> seconds. If <VAR +CLASS="PARAMETER" +>wait</VAR +> +is less than one, the wait interval is set to one second. When the +<VAR +CLASS="OPTION" +>-w</VAR +> option is used, <B +CLASS="COMMAND" +>host</B +> will +effectively wait forever for a reply. The time to wait for a response +will be set to the number of seconds given by the hardware's maximum +value for an integer quantity.</P +></DIV +><DIV +CLASS="REFSECT1" +><A +NAME="AEN115" +></A +><H2 +>FILES</H2 +><P +><TT +CLASS="FILENAME" +>/etc/resolv.conf</TT +></P +></DIV +><DIV +CLASS="REFSECT1" +><A +NAME="AEN119" +></A +><H2 +>SEE ALSO</H2 +><P +><SPAN +CLASS="CITEREFENTRY" +><SPAN +CLASS="REFENTRYTITLE" +>dig</SPAN +>(1)</SPAN +>, +<SPAN +CLASS="CITEREFENTRY" +><SPAN +CLASS="REFENTRYTITLE" +>named</SPAN +>(8)</SPAN +>.</P +></DIV +></BODY +></HTML +> |
