    PHP:
    <?php
    echo gethostbyname('ya.ru');
    ?>
    Выдает мне
    Code:
    ya.ru

    хм, а у меня работает все.
    код:

    <form method="post">
    <input type="text" name="text">
    <input type="submit" name="button" value="CheckIT">
    </form>

    <?php
    if (isset($_POST['button'])) {
    $i = $_POST['text'];
    echo gethostbyname($i);
    }
    ?>

    да емае. понятно что у вас он работает. вот у меня на ноуте работает на компе нет. Стоит Linux
    Code:
    ping yandex.ru
    PING yandex.ru (87.250.251.11) 56(84) bytes of data.
    64 bytes from yandex.ru (87.250.251.11): icmp_seq=1 ttl=57 time=26.5 ms
    64 bytes from yandex.ru (87.250.251.11): icmp_seq=2 ttl=57 time=28.3 ms
    
    ...значит с ДНС все норм

    echo gethostbyname('ya.ru');

    Code:
    [root@localhost ~]#[root@localhost ~]# iptables -L
    Chain INPUT (policy ACCEPT)
    target     prot opt source               destination         
    
    Chain FORWARD (policy ACCEPT)
    target     prot opt source               destination         
    
    Chain OUTPUT (policy ACCEPT)
    target     prot opt source               destination         
       
    что еще может закрыть 80 порт?
