//Datos para la DB
 
$host = "localhost";
$userw = "root";
$passw = "";
$db = "ban";
 
//
 
mysql_connect($host,$userw,$passw);
mysql_select_db($db);
 
$ipa = ip2long($_SERVER[REMOTE_ADDR]);
$ip = $_SERVER[REMOTE_ADDR];
 
if ($ipa == -1 || $ipa === FALSE) {
 
$re = mysql_query("select ip from bansystem where ip='$ip'");
 
if (mysql_num_rows($re) > 0) {
echo "<center><h1>Has sido baneado de esta pagina</h1></center>";
} else {
echo "<center><h2>Bienvenido</h2></center>";
