NAME
    host - DNS lookup utility

SYNOPSIS
    host [ -aCdlnrTwv ] [ -c class ] [ -N ndots ] [ -R number ] [ -t
    type ] [ -W wait ] name [ server ]

DESCRIPTION
    host is a simple utility for performing DNS lookups.  It is normally
    used to  convert names to IP addresses and vice versa.  When no argu-
    ments or options are given, host prints a short summary of its command
    line arguments and options.

    name is the domain name that is to be looked up. It can also be a dot-
    ted-decimal IPv4 address or a colon-delimited IPv6 address, in  which
    case host will  by default perform a reverse lookup for that address.
    server is an optional argument which is either the name or IP address
    of the name server that host should query instead of the server or
    servers listed in /etc/resolv.conf.

    The -a (all) option is equivalent to setting the -v option and asking
    host to make a query of type ANY.

    When the -C option is used,  host will attempt to display the SOA
    records for zone name 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.

    The -c option instructs to make a DNS query of class class. This can be
    used to  lookup Hesiod or Chaosnet class resource records. The default
    class is IN (Internet).

    Verbose output is generated by host when the -d or -v option is  used.
    The two  options are equivalent. They have been provided for backwards
    compatibility. In previous versions, the -d option switched on debug-
    ging traces and -v enabled verbose output.

    List mode is selected by the -l option. This makes host perform a zone
    transfer for zone name. The argument is provided for compatibility with
    older implemementations. This option is equivalent to making a query of
    type AXFR.

    The -n option specifies that reverse lookups of IPv6 addresses should
    use the IP6.INT domain and "nibble" labels as defined in RFC1886. The
    default is to use IP6.ARPA and binary labels as defined in RFC2874.

    The -N option sets the number of dots that have to be in name for it to
    be considered absolute. The default value is that defined using the
    ndots statement in /etc/resolv.conf, 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 search or domain
    directive in /etc/resolv.conf.

    The number of UDP retries for a lookup can be changed with the -R
    option. number indicates how many times host will repeat a query that
    does not get answered. The default number of retries is 1. If number is
    negative or zero, the number of retries will default to 1.

    Non-recursive queries can be made via the -r option.  Setting this
