title: What DNS Name Label should I give my Azure Virtual Machine?
body: <p>In my ongoing effort to wrap my head around Azure's new Resource Group model (see previous questions <a href="https://stackoverflow.com/questions/35163948/associate-a-public-ip-in-an-azure-resource-group-to-a-web-app">here</a> and <a href="https://stackoverflow.com/questions/35183153/point-ip-address-to-azure-resource-group-web-app/35183280?noredirect=1#comment58138836_35183280">here</a>), I am now trying to create a new Virtual Machine that will be used as a web server.</p>
  
  <p>I have thee questions:</p>
  
  <p><strong>Question One:</strong></p>
  
  <p>Assuming I eventually want this VM to host the website woodswild.com, what DNS Name Label should I give this VM? Does it matter?  All I know for sure is that it needs to be globally unique. Does it need to reflect the domain I want to host (woodswild.com)?</p>
  
  <p><strong>Question Two:</strong></p>
  
  <p>Do I even need to set the DNS name at all?</p>
  
  <p><strong>Question Three:</strong></p>
  
  <p>And, now that I've already created it, can I still change the DNS Name Label from "none" to something? And if so, how?</p>
