It's not a best practice. Insight (analyse by Sensio) returns : "Using PHP response functions (like header() here) is discouraged, as it bypasses the Symfony event system. Use the HttpFoundationResponse class instead." and "$_SERVER super global should not be used."

getClientIp();
$authorized_hosts = ['127.0.0.1', 'fe80::1', '::1', 'localhost', 'yourIpAddress'];

// Securisation
if (!in_array($client_ip, $authorized_hosts)) {
    $response = new Response(
        "Forbidden",
        Response::HTTP_FORBIDDEN,
        array('content-type' => 'text/html')
    );
    $response->send();
    exit();
}

$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

It's ok for SensioInsight
