Net::Whois::Raw(3)

NAME
Net::Whois::Raw - Get Whois information for domains

SYNOPSIS
  use Net::Whois::Raw;

  $s = whois('perl.com');
  $s = whois('funet.fi');

  $arrayref = get_whois('yahoo.co.uk', undef, 'QRY_ALL');
  $text = get_whois('yahoo.co.uk', undef, 'QRY_LAST');
  ($text, $srv) = get_whois('yahoo.co.uk', undef, 'QRY_FIRST');

  ### if you do "use Net::Whois::Raw qw(
  #     $OMIT_MSG $CHECK_FAIL $CHECK_EXCEED
  #     $CACHE_DIR $CACHE_TIME $USE_CNAMES $TIMEOUT @SRC_IPS );
  ### you can use these:

  $OMIT_MSG = 1; # This will attempt to strip several known copyright
                messages and disclaimers sorted by servers.
                Default is to give the whole response.

  $OMIT_MSG = 2; # This will try some additional stripping rules
                if none are known for the spcific server.

  $CHECK_FAIL = 1; # This will return undef if the response matches
                one of the known patterns for a failed search,
                sorted by servers.
                Default is to give the textual response.

  $CHECK_FAIL = 2; # This will match against several more rules
                if none are known for the specific server.

  $CHECK_EXCEED = 1; # When this option is set, "die" will be called
                if connection rate to specific whois server have been
                exceeded

  $CACHE_DIR = "/var/spool/pwhois/"; # Whois information will be
                cached in this directory. Default is no cache.

  $CACHE_TIME = 60; # Cache files will be cleared after not accessed
                for a specific number of minutes. Documents will not be
                cleared if they keep get requested for, independent
                of disk space. Default is not to clear the cache.

  $USE_CNAMES = 1; # Use whois-servers.net to get the whois server
                name when possible. Default is to use the
                hardcoded defaults.

  $TIMEOUT = 10; # Cancel the request if connection is not made within
                a specific number of seconds.

  @SRC_IPS = (11.22.33.44); # List of local IP addresses to
                use for WHOIS queries. Addresses will be used used
                successively in the successive queries

DESCRIPTION
Net::Whois::Raw queries WHOIS servers about domains. The module supports recursive WHOIS queries. Also queries via HTTP is supported for some TLDs.

Setting the variables $OMIT_MSG and $CHECK_FAIL will match the results against a set of known patterns. The first flag will try to omit the copyright message/disclaimer, the second will attempt to determine if the search failed and return undef in such a case.

IMPORTANT: these checks merely use pattern matching; they will work on several servers but certainly not on all of them.

FUNCTIONS

whois( DOMAIN [, SRV [, WHICH_WHOIS]] )
    Returns Whois information for "DOMAIN". Without "SRV" argument default Whois server for specified domain name zone will be used. Use 'www_whois' as server name to force WHOIS querying via HTTP (only few TLDs are supported in HTTP queries). Caching is supported: if $CACHE_DIR variable is set and there is cached entry for that domain - information from the cache will be used. "WHICH_WHOIS" argument - look get_whois docs below.

get_whois( DOMAIN [, SRV [, WHICH_WHOIS]] )
    Lower-level function to query Whois information for "DOMAIN". Caching IS NOT supported (caching is implemented only in higher-level "whois" function). Without "SRV" argument default Whois server for specified domain name zone will be used. "WHICH_WHOIS" argument is used to access a results if recursive queries; possible values:

    'QRY_FIRST' -
        returns results of the first query. Non't make recursive queries.
        In scalar context returns just whois text.
        In list context returns two values: whois text and whois server
        which was used to make query).

    'QRY_LAST' -
        returns results of the last query.
        In scalar context returns just whois text.
        In list context returns two values: whois text and whois server
        which was used to make query).
        This is the default option.

    'QRY_ALL' -
        returns results of the all queries of the recursive chain.
        Reference to array of references to hashes is returned.
        Hash keys: "text" - result of whois query, "srv" -
        whois server which was used to make query.
