Description:
------------
PHP can not do DNS-resolution,
all other software or parts of the OS can.

Reproduce code:
---------------
$foo = gethostbyaddr('69.147.83.197');
echo 'gethostbyaddr [should show a hostname] : '.$foo."\n";

$foo = gethostbyname("php.net");
echo 'gethostbyname [should show an ip] : '.$foo."\n";

$host = explode('@', '[EMAIL PROTECTED]');
if(!checkdnsrr($host[1].'.', 'MX') ) {
        echo "No MX record found for [EMAIL PROTECTED]";
}

Expected result:
----------------
gethostbyaddr [should show a hostname] : y2.php.net
gethostbyname [should show an ip] : 69.147.83.197

Actual result:
--------------
gethostbyaddr [should show a hostname] : 69.147.83.197
gethostbyname [should show an ip] : php.net
No MX record found for [EMAIL PROTECTED]
