title: Does the * in a CNAME record take priority over explicit subdomains?
body: <p>I have a set of subdomains defined on my domain like this:</p>
  
  <pre><code>CNAME sub1.example.com -&gt; sub1.herokuapp.com
  CNAME sub2.example.com -&gt; sub2.appspot.com
  CNAME www.example.com -&gt; example.herokuapp.com
  </code></pre>
  
  <p>Now I'd like to add <code>CNAME *.example.com -&gt; example.herokuapp.com</code> to catch folks who put in too many WWWs or type in other missing subdomains. But will the <code>*</code> take priority over the explicitly defined subdomains or will the subdomains continue to work as expected?</p>
  
  <p>I'm using Route53 if it makes a difference. </p>
