All of the sites I have hosted in IIS have host header bindings, and I've disabled the Default Website. Right now, if someone hits http(s)://<ipaddress> they still get a 404 response from the server.
Is there a way to get IIS to not even respond to a request with no host headers (or a request with host headers that aren't bound)? On nginx, commonly you'll have the server return a status of 444 if no bindings are found, which instructs the server to drop the connection with no response.
