TMTOWTDI, of course, but I'd prefer to say: 

#!/usr/bin/perl

use strict;
use warnings;
 
use IO::Socket::INET;
 
my @host = qw[ 192.168.1.3 192.168.46.2 ];
my $port = 22;
 
foreach (@host)
{
     check($_, $port);
}
 
sub check {
     my ($ip, $port) = @_;

     print 
     (
          my $sock = IO::Socket::INET->new(
                         PeerAddr => $ip,
                         PeerPort => $port,
                         Proto    => 'tcp',
                         timeout  => 10,
          )
     ?    "$ip is listening on port $port\n"
     :    "$ip is NOT listening on port $port.\n"
     )
}

But then again, I'm a sucker for the ternary operator.
