Whois(3pm) User Contributed Perl Documentation Whois(3pm)NAME
Whois - Perl extension to make queries to the whois servers
SYNOPSIS
use Whois;
$whois = new Whois('Host' => 'whois.ripe.net');
die("Failed to create object") unless(ref($whois));
die($whois->GetError()) if($whois->GetError());
if($whois->Query("BAT-RIPE")) {
printf("Query error: %s
", $whois->GetError());
exit;
}
my $result = $whois->GetResult();
if($result) {
print "$result
";
}
else {
printf("No results: %s
", $whois->GetError());
}
$whois->Close();
DESCRIPTION
Stub documentation for Whois was created by h2xs. It looks like the author of the extension was negligent enough to leave the stub
unedited.
Blah blah blah.

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();
};
