+.SH NAME
+host \- DNS lookup utility
+.SH SYNOPSIS
+.sp
+\fBhost\fP [\fB\-aACdlnrsTUwv\fP] [\fB\-c\fP class] [\fB\-N\fP ndots] [\fB\-p\fP port] [\fB\-R\fP number] [\fB\-t\fP type] [\fB\-W\fP wait] [\fB\-m\fP flag] [ [\fB\-4\fP] | [\fB\-6\fP] ] [\fB\-v\fP] [\fB\-V\fP] {name} [server]
+.SH DESCRIPTION
+.sp
+\fBhost\fP is a simple utility for performing DNS lookups. It is normally
+used to convert names to IP addresses and vice versa. When no arguments
+or options are given, \fBhost\fP prints a short summary of its
+command\-line arguments and options.
+.sp
+\fBname\fP 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\fP by default performs a reverse lookup for that address.
+\fBserver\fP is an optional argument which is either the name or IP
+address of the name server that \fBhost\fP should query instead of the
+server or servers listed in \fB/etc/resolv.conf\fP\&.
+.SH OPTIONS
+.INDENT 0.0
+.TP
+.B \fB\-4\fP
+This option specifies that only IPv4 should be used for query transport. See also the \fB\-6\fP option.
+.TP
+.B \fB\-6\fP
+This option specifies that only IPv6 should be used for query transport. See also the \fB\-4\fP option.
+.TP
+.B \fB\-a\fP
+The \fB\-a\fP (\(dqall\(dq) option is normally equivalent to \fB\-v \-t ANY\fP\&. It
+also affects the behavior of the \fB\-l\fP list zone option.
+.TP
+.B \fB\-A\fP
+The \fB\-A\fP (\(dqalmost all\(dq) option is equivalent to \fB\-a\fP, except that RRSIG,
+NSEC, and NSEC3 records are omitted from the output.
+.TP
+.B \fB\-c class\fP
+This option specifies the query class, which can be used to lookup HS (Hesiod) or CH (Chaosnet)
+class resource records. The default class is IN (Internet).
+.TP
+.B \fB\-C\fP
+This option indicates that \fBnamed\fP should check consistency, meaning that \fBhost\fP queries the SOA records for zone
+\fBname\fP 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.
+.TP
+.B \fB\-d\fP
+This option prints debugging traces, and is equivalent to the \fB\-v\fP verbose option.
+.TP
+.B \fB\-l\fP
+This option tells \fBnamed\fP to list the zone, meaning the \fBhost\fP command performs a zone transfer of zone
+\fBname\fP and prints out the NS, PTR, and address records (A/AAAA).
+.sp
+Together, the \fB\-l \-a\fP options print all records in the zone.
+.TP
+.B \fB\-N ndots\fP
+This option specifies the number of dots (\fBndots\fP) that have to be in \fBname\fP for it to be
+considered absolute. The default value is that defined using the
+\fBndots\fP statement in \fB/etc/resolv.conf\fP, or 1 if no \fBndots\fP statement
+is present. Names with fewer dots are interpreted as relative names,
+and are searched for in the domains listed in the \fBsearch\fP or
+\fBdomain\fP directive in \fB/etc/resolv.conf\fP\&.
+.TP
+.B \fB\-p port\fP
+This option specifies the port to query on the server. The default is 53.
+.TP
+.B \fB\-r\fP
+This option specifies a non\-recursive query; setting this option clears the RD (recursion
+desired) bit in the query. This means that the name server
+receiving the query does not attempt to resolve \fBname\fP\&. The \fB\-r\fP
+option enables \fBhost\fP to mimic the behavior of a name server by
+making non\-recursive queries, and expecting to receive answers to
+those queries that can be referrals to other name servers.
+.TP
+.B \fB\-R number\fP
+This option specifies the number of retries for UDP queries. If \fBnumber\fP is negative or zero,
+the number of retries is silently set to 1. The default value is 1, or
+the value of the \fBattempts\fP option in \fB/etc/resolv.conf\fP, if set.
+.TP
+.B \fB\-s\fP
+This option tells \fBnamed\fP \fInot\fP 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.
+.TP
+.B \fB\-t type\fP
+This option specifies the query type. The \fBtype\fP argument can be any recognized query type:
+CNAME, NS, SOA, TXT, DNSKEY, AXFR, etc.
+.sp
+When no query type is specified, \fBhost\fP automatically selects an
+appropriate query type. By default, it looks for A, AAAA, and MX
+records. If the \fB\-C\fP option is given, queries are made for SOA
+records. If \fBname\fP is a dotted\-decimal IPv4 address or
+colon\-delimited IPv6 address, \fBhost\fP queries for PTR records.
+.sp
+If a query type of IXFR is chosen, the starting serial number can be
+specified by appending an equals sign (=), followed by the starting serial
+number, e.g., \fB\-t IXFR=12345678\fP\&.
+.TP
+.B \fB\-T\fP; \fB\-U\fP
+This option specifies TCP or UDP. By default, \fBhost\fP uses UDP when making queries; the
+\fB\-T\fP option makes it use a TCP connection when querying the name
+server. TCP is automatically selected for queries that require
+it, such as zone transfer (AXFR) requests. Type \fBANY\fP queries default
+to TCP, but can be forced to use UDP initially via \fB\-U\fP\&.
+.TP
+.B \fB\-m flag\fP
+This option sets memory usage debugging: the flag can be \fBrecord\fP, \fBusage\fP, or
+\fBtrace\fP\&. The \fB\-m\fP option can be specified more than once to set
+multiple flags.
+.TP
+.B \fB\-v\fP
+This option sets verbose output, and is equivalent to the \fB\-d\fP debug option. Verbose output
+can also be enabled by setting the \fBdebug\fP option in
+\fB/etc/resolv.conf\fP\&.
+.TP
+.B \fB\-V\fP
+This option prints the version number and exits.
+.TP
+.B \fB\-w\fP
+This option sets \(dqwait forever\(dq: the query timeout is set to the maximum possible. See
+also the \fB\-W\fP option.
+.TP
+.B \fB\-W wait\fP
+This options sets the length of the wait timeout, indicating that \fBnamed\fP should wait for up to \fBwait\fP seconds for a reply. If \fBwait\fP is
+less than 1, the wait interval is set to 1 second.
+.sp
+By default, \fBhost\fP waits for 5 seconds for UDP responses and 10
+seconds for TCP connections. These defaults can be overridden by the
+\fBtimeout\fP option in \fB/etc/resolv.conf\fP\&.
+.sp
+See also the \fB\-w\fP option.
+.UNINDENT
+.SH IDN SUPPORT
+.sp
+If \fBhost\fP has been built with IDN (internationalized domain name)
+support, it can accept and display non\-ASCII domain names. \fBhost\fP
+appropriately converts character encoding of a domain name before sending
+a request to a DNS server or displaying a reply from the server.
+To turn off IDN support, define the \fBIDN_DISABLE\fP
+environment variable. IDN support is disabled if the variable is set
+when \fBhost\fP runs.
