It is normally used to convert names to IP addresses and vice versa. When no arguments or options are given, -\fBhost\fR -prints a short summary of its command line arguments and options. -.PP -\fIname\fR -is the domain name that is to be looked up. It can also be a dotted\-decimal IPv4 address or a colon\-delimited IPv6 address, in which case -\fBhost\fR -will by default perform a reverse lookup for that address. -\fIserver\fR -is an optional argument which is either the name or IP address of the name server that -\fBhost\fR -should query instead of the server or servers listed in -\fI/etc/resolv.conf\fR. -.PP -The -\fB\-a\fR -(all) option is equivalent to setting the -\fB\-v\fR -option and asking -\fBhost\fR -to make a query of type ANY. -.PP -When the -\fB\-C\fR -option is used, -\fBhost\fR -will attempt to display the SOA records for zone -\fIname\fR -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. -.PP -The -\fB\-c\fR -option instructs to make a DNS query of class -\fIclass\fR. This can be used to lookup Hesiod or Chaosnet class resource records. The default class is IN (Internet). -.PP -Verbose output is generated by -\fBhost\fR -when the -\fB\-d\fR -or -\fB\-v\fR -option is used. The two options are equivalent. They have been provided for backwards compatibility. In previous versions, the -\fB\-d\fR -option switched on debugging traces and -\fB\-v\fR -enabled verbose output. -.PP -List mode is selected by the -\fB\-l\fR -option. This makes -\fBhost\fR -perform a zone transfer for zone -\fIname\fR. Transfer the zone printing out the NS, PTR and address records (A/AAAA). If combined with -\fB\-a\fR -all records will be printed. -.PP -The -\fB\-i\fR -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. -.PP -The -\fB\-N\fR -option sets the number of dots that have to be in -\fIname\fR -for it to be considered absolute. The default value is that defined using the ndots statement in -\fI/etc/resolv.conf\fR, 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 -\fBsearch\fR -or -\fBdomain\fR -directive in -\fI/etc/resolv.conf\fR. -.PP -The number of UDP retries for a lookup can be changed with the -\fB\-R\fR -option. -\fInumber\fR -indicates how many times -\fBhost\fR -will repeat a query that does not get answered. The default number of retries is 1. If -\fInumber\fR -is negative or zero, the number of retries will default to 1. -.PP -Non\-recursive queries can be made via the -\fB\-r\fR -option. Setting this option clears the -\fBRD\fR -\(em recursion desired \(em bit in the query which -\fBhost\fR -makes. This should mean that the name server receiving the query will not attempt to resolve -\fIname\fR. The -\fB\-r\fR -option enables -\fBhost\fR -to mimic the behavior 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. -.PP -By default -\fBhost\fR -uses UDP when making queries. The -\fB\-T\fR -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. -.PP -The -\fB\-4\fR -option forces -\fBhost\fR -to only use IPv4 query transport. The -\fB\-6\fR -option forces -\fBhost\fR -to only use IPv6 query transport. -.PP -The -\fB\-t\fR -option is used to select the query type. -\fItype\fR -can be any recognized query type: CNAME, NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified, -\fBhost\fR -automatically selects an appropriate query type. By default it looks for A records, but if the -\fB\-C\fR -option was given, queries will be made for SOA records, and if -\fIname\fR -is a dotted\-decimal IPv4 address or colon\-delimited IPv6 address, -\fBhost\fR -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). -.PP -The time to wait for a reply can be controlled through the -\fB\-W\fR -and -\fB\-w\fR -options. The -\fB\-W\fR -option makes -\fBhost\fR -wait for -\fIwait\fR -seconds. If -\fIwait\fR -is less than one, the wait interval is set to one second. When the -\fB\-w\fR -option is used, -\fBhost\fR -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. -.PP -The -\fB\-s\fR -option tells -\fBhost\fR -\fInot\fR -to send the query to the next nameserver if any server responds with a SERVFAIL response, which is the reverse of normal stub resolver behavior. -.PP -The -\fB\-m\fR -can be used to set the memory usage debugging flags -\fIrecord\fR, -\fIusage\fR -and -\fItrace\fR. -.SH "IDN SUPPORT" -.PP -If -\fBhost\fR -has been built with IDN (internationalized domain name) support, it can accept and display non\-ASCII domain names. -\fBhost\fR -appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server. If you'd like to turn off the IDN support for some reason, defines the -\fBIDN_DISABLE\fR -environment variable. The IDN support is disabled if the variable is set when -\fBhost\fR -runs. -.SH "FILES" -.PP -\fI/etc/resolv.conf\fR -.SH "SEE ALSO" -.PP -\fBdig\fR(1), -\fBnamed\fR(8). -.SH "COPYRIGHT" -Copyright \(co 2004, 2005, 2007 Internet Systems Consortium, Inc.
