Why the '+' sign in the packet data? I tried this:

$sock->print("n 8.8.8.8.\n");

And it works fine. Windows 7 x64, Strawberry 5.18.1:

VinsWorldcom@C:\Users\VinsWorldcom\tmp> cat test.pl
use strict;
use warnings;

use Data::Dumper;
use IO::Socket;

my %whois_servers = (
  "RIPE"=>"whois.ripe.net",
  "APNIC"=>"whois.apnic.net",
  "KRNIC"=>"whois.krnic.net",
  "LACNIC"=>"whois.lacnic.net",
  "ARIN"=>"whois.arin.net",
  "AFRINIC"=>"whois.afrinic.net",
);

my $sock = IO::Socket::INET->new(
  PeerAddr=>$whois_servers{ARIN},
  PeerPort=>'43',
  Timeout=>'60',
);

$sock->print("n 8.8.8.8\n");
my @ret = <$sock>;
@ret = grep {length($_)} map { s/\n//; $_ } @ret;

print Dumper(\@ret);
