title: AWS Route53: Private and public hosted zones under the same domain
body: <p>I've read through all the AWS docs I can find and GoogleFoo has not resulted in anything.</p>
  
  <p>My case here is we have one domain example.com and up to now we have used it only for Public records. There is one Hosted Zone set to Public. I want to now create a subdomain for private records to use inside of our VPC group for our application (e.g. to point at an ElastiCache instance).</p>
  
  <p>I attempted to create private.example.com as a Private Hosted Zone pointing at our VPC and then created cache.private.example.com as a record under it but it will not resolve.</p>
  
  <p>I am curious if I can configure a subdomain of our main domain somehow?</p>
  
  <pre><code>example.com - Public
  ** app.example.com 
  private.example.com - Private
  ** cache.private.example.com - VPC
  </code></pre>
  
  <p>OR</p>
  
  <p>Can also create a Private Hosted Zone with the same top level domain example.com? I am nervous to try that because I do not want to affect the application. </p>
  
  <pre><code>example.com - Public
  ** app.example.com
  example.com - Private
  ** cache.example.com - VPC
  </code></pre>
