Block IP Addresses using Code [closed]

Place in your template’s index.php the following piece of code:

$deny = array("127.0.0.1", "88.88.88.88");

if (in_array ($_SERVER['REMOTE_ADDR'], $deny)) 
{
    header("Location: http://example.com");
    die();
}

And just change the addresses of $deny for the IP address or addresses you want to block.
