title: What top-level domains does youtube have?
body: <p>I am trying to identify youtube link (generally), and I wonder what top-level domains is youtube using?</p>
  
  <p>So far I know about:</p>
  
  <ul>
  <li>.com (youtube.com)</li>
  <li>.be (youtu.be)</li>
  </ul>
  
  <p>Are there any others?</p>
