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.
