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 = 0 | 1 | 2;
        # When this option is true, "die" will be called
        # if connection rate to specific whois server have been
        # exceeded.
        # If set to 2, will die in recursive queries too.

    $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';

    $Net::Whois::Raw::QUERY_SUFFIX = '/e';
        # This will add specified suffix to whois query.
        # It may be used for english output forcing.

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();
    };
set_ips_for_server('whois.ripn.net', ['127.0.0.1']);

You can specify IPs list which will be used for queries to desired whois server. It can be useful if you have few interfaces, but you need to access whois server from specified ips.
