title: IIS: add binding to Default Web Site
body: <p>I just started looking at IIS on Windows10.</p>
  
  <p>I have a stupid question. I added a binding to Default Web Site ("www.test.com") in  IIS Manager.</p>
  
  <p>I was expecting to see the default page when browsing to this url, but it took me instead to an actual existing page.</p>
  
  <p>Can anyone explain me why?</p>
