NAME¶

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

SYNOPSIS¶

  use Net::Whois::Raw;
  $dominfo = whois('perl.com');
  ($dominfo, $whois_server) = whois('funet.fi');
  $reginfo = whois('REGRU-REG-RIPN', 'whois.ripn.net');
  $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');
  $Net::Whois::Raw::OMIT_MSG = 1;
        # This will attempt to strip several known copyright
        # messages and disclaimers sorted by servers.
        # Default is to give the whole response.
  $Net::Whois::Raw::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.
  $Net::Whois::Raw::CHECK_EXCEED = 1;
        # When this option is set, "die" will be called
        # if connection rate to specific whois server have been
        # exceeded
  $Net::Whois::Raw::CACHE_DIR = "/var/spool/pwhois/";
        # Whois information will be
        # cached in this directory. Default is no cache.
  $Net::Whois::Raw::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.
  $Net::Whois::Raw::TIMEOUT = 10;
        # Cancel the request if connection is not made within
        # a specific number of seconds.
  @Net::Whois::Raw::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
  $Net::Whois::Raw::POSTPROCESS{whois.crsnic.net} = \&my_func;
        # Call to a user-defined subroutine on whois result,
        # depending on whois-server.
        # Above is equil to:
        # ($text, $srv) = whois('example.com');
        # $text = my_func($text) if $srv eq 'whois.crsnic.net';

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.

USER DEFINED FUNCTIONS¶

whois_query_sockparams( DOMAIN, SRV )

You can set your own IO::Socket::INET params like this:

    *Net::Whois::Raw::whois_query_sockparams = sub {
        my $class  = shift;
        my $domain = shift;
        my $name   = shift;
        return (
            PeerAddr => $name,
            PeerPort => 43,
            # LocalHost => ,
            # LocalPort =>
        );
    };
    

whois_query_socket( DOMAIN, SRV )

You can set your own IO::Socket::INET like this:

    *Net::Whois::Raw::whois_query_socket = sub {
        my $class  = shift;
        my $domain = shift;
        my $name   = shift;
        $name .= ':43';
        return IO::Socket::INET->new();
    };
    

whois_query_ua( DOMAIN, SRV )

You can set your own LWP::UserAgent like this:

    *Net::Whois::Raw::whois_query_ua = sub {
        my $class  = shift;
        my $domain = shift;
        return LWP::UserAgent->new();
    };
