title: Not using 'localhost' in HOST for development with create-react-app
body: <p>My problem is quite simple: I would like to avoid using <code>localhost</code> at the end of my <code>HOST</code> env variable with create-react-app. However it seems that if the URL doesn't end with <code>.localhost</code>, the script will try to resolve the URL against a DNS server.</p>
  
  <p>I would like to avoid that and just use the same URL domain as my backend server is using, to avoid CORS problems (and I wish not to configure my backend to allow CORS because that's not how the production infrastructure is).</p>
  
  <p>Thanks :)</p>
