title: Preview new website without editing vhosts on customers device
body: <p>I have an existing website on domain e.g.: '123.com' hosted in company A. </p>
  
  <p>On the other hand I have my server in company B, created the account for '123.com' and a new wordpress site.</p>
  
  <p>I can preview the new website by editing vhosts file on mac-OS, but if I want the client to preview the new site on the same domain? </p>
  
  <p>I tried once with one client to edit vhosts file but was imposible, as he had no knowledge about vhosts. </p>
  
  <p>Any ideas? </p>
