How to fix IP-Based voting?

I have IP based voting code, but the problem is when I vote from my computer ( connected to the internet using the same network ) I can't !!

Here is the code : 

global $wpdb;
$post_ID = $_POST['id'];
$ip = $_SERVER['REMOTE_ADDR'];
$irt_textOnclick = get_option('irt_textOnclick');
$recommend = get_post_meta($post_ID, '_recommended', true);

if($post_ID != '') {
    $voteStatusByIp = $wpdb->get_var("SELECT COUNT(*) FROM ".$wpdb->prefix."irecommendthis_votes WHERE post_id = '$post_ID' AND ip = '$ip'");

    if (!isset($_COOKIE['recommended-'.$post_ID]) && $voteStatusByIp == 0) {
        $recommendNew = $recommend + 1;
        update_post_meta($post_ID, '_recommended', $recommendNew);

        setcookie('recommended-'.$post_ID, time(), time()+3600*24*365, '/');
        $wpdb->query("INSERT INTO ".$wpdb->prefix."irecommendthis_votes VALUES ('', NOW(), '$post_ID', '$ip')");

        $return_text = $recommendNew . ' ' . $irt_textOnclick;
        echo $return_text; //$recommendNew; // 
    }
    else {
        $return_text = $recommend . ' ' . $irt_textOnclick;
        echo $return_text; //$recommendNew; //  
    }
}

If you are using both cookies and IP checks to prevent multiple voting, then votes cannot be done more than once for computers sharing the same IP address. That would prevent other users in the same network from making votes, since you would be considered as having one IP address.
