title: Is there any option to know from which Wifi/network request comment?
body: <p>I plan to make a web application. The workflow will be the client scan QR code using his phone to go to some specific URL.</p>
  <p>But interested to me is there any option to I can limit visit that URL if the request didn't comment from a specific WiFi network? I do not want to anybody take a photo and fake requests.</p>
