title: AWS Route 53 Listing CNAME Records using boto3
body: <p>I want to list all the CNAME records in a certain hosted zone. Let's say I have over 400 records in my hosted zone. I'm using <code>boto3</code>:</p>
  
  <pre><code>response_per_zone = client.list_resource_record_sets(HostedZoneId=Id, MaxItems='100')
  </code></pre>
  
  <p>This command list 100 records of all types. There is a lot of CNAME records missing.<br>
  How do I iterate through all the records so that I can list all the CNAME records?</p>
