title: DNS Map sub domain to another sub domain, which records?
body: <p>I have a master domain name:</p>
  
  <pre><code>exampledev.co.uk
  </code></pre>
  
  <p>and an administration panel at:</p>
  
  <pre><code>admin.exampledev.co.uk
  </code></pre>
  
  <p>We then have a client:</p>
  
  <pre><code>exampleclient.co.uk
  </code></pre>
  
  <p>What I want to do is, map a subdomain:</p>
  
  <pre><code>admin.exampleclient.co.uk
  </code></pre>
  
  <p>to</p>
  
  <pre><code>admin.exampledev.co.uk
  </code></pre>
  
  <p>All of these sites will be stored on the same server. The idea is that on <code>admin.exampledev.co.uk</code>, it will use the HTTP_HOST variable to determine which admin database to load.</p>
  
  <p>Which DNS record do I change to do this?</p>
