("ISC") + + + + + + host + + + + + + + + + + + + + + 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 arguments 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 dotted-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. + + + + + OPTIONS + + + + + -4 + + + Use IPv4 only for query transport. + See also the option. + + + + + + -6 + + + Use IPv6 only for query transport. + See also the option. + + + + + + -a + + + "All". The option is normally equivalent + to . + It also affects the behaviour of the + list zone option. + + + + + + -c class + + + Query class: This can be used to lookup HS (Hesiod) or CH + (Chaosnet) class resource records. The default class is IN + (Internet). + + + + + + -C + + + Check consistency: host will query 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. + + + + + + -d + + + Print debugging traces. + Equivalent to the verbose option. + + + + + + -i + + + Obsolete. + Use the IP6.INT domain for reverse lookups of IPv6 + addresses as defined in RFC1886 and deprecated in RFC4159. + The default is to use IP6.ARPA as specified in RFC3596. + + + + + + -l + + + List zone: + The host command performs a zone transfer of + zone name and prints out the NS, + PTR and address records (A/AAAA). + + + Together, the + options print all records in the zone. + + + + + + -N ndots + + + 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. + + + + + + -r + + + Non-recursive query: + Setting this option clears the RD (recursion desired) bit + in the query. This should mean that the name server + receiving the query will not attempt to + resolve name. + The option + enables host 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. + + + + + + -R number + + + Number of retries for UDP queries: + If number is negative or zero, the + number of retries will default to 1. The default value is + 1, or the value of the attempts + option in /etc/resolv.conf, if set. + + + + + + -s + + + Do not send the query to the next + nameserver if any server responds with a SERVFAIL + response, which is the reverse of normal stub resolver + behavior. + + + + + + -t type + + + Query type: + The type argument can be any + recognized query type: CNAME, NS, SOA, TXT, DNSKEY, AXFR, etc. + + + When no query type is specified, host + automatically selects an appropriate query type. By default, it + looks for A, AAAA, and MX records. + If the option is given, queries will + be made for SOA records. + If name is a dotted-decimal IPv4 + address or colon-delimited IPv6 + address, host 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 + (like ). + + + + + + -T + -U + + + TCP/UDP: + By default, host uses UDP when making + queries. The 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. Type ANY queries default + to TCP but can be forced to UDP initially using . + + + + + + -m flag + + + Memory usage debugging: the flag can + be record, usage, + or trace. You can specify + the option more than once to set + multiple flags. + + + + + + -v + + + Verbose output. + Equivalent to the debug option. + Verbose output can also be enabled by setting + the debug option + in /etc/resolv.conf. + + + + + + -V + + + Print the version number and exit. + + + + + + -w + + + Wait forever: The query timeout is set to the maximum possible. + See also the option. + + + + + + -W wait + + + Timeout: Wait for up to wait + seconds for a reply. If wait is + less than one, the wait interval is set to one second. + + + By default, host will wait for 5 + seconds for UDP responses and 10 seconds for TCP + connections. These defaults can be overridden by + the timeout option + in /etc/resolv.conf. + + + See also the option. + + + + + + + + + IDN SUPPORT + + + If host has been built with IDN (internationalized + domain name) support, it can accept and display non-ASCII domain names. + host 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 IDN_DISABLE environment variable. + The IDN support is disabled if the variable is set when + host runs. + + + + FILES + + /etc/resolv.conf + + + + SEE ALSO + + + dig1 + , + + named8 + . + + + + -- cgit v1.2.3
