title: Doing a whois with a list of domain names
body: <p>I've got a file of domain names e.g. equivalent to 2500.</p>
  
  <p>I would like to do a whois on these domain names. </p>
  
  <p>Issue is I've never done that and don't know where to start. If you have any ideas, I'm all ears.</p>
  
  <p>TIA.</p>
