  -**Root domain**: Some DNS providers support using an alternative custom record type, such as ANAME or ALIAS, for configuring custom zone apex domains. These domains are also known as root domains. ANAME and ALIAS records follow the pattern below:

  +
  +Use a DNS CNAME record to alias a multi-level custom subdomain.
  +
  + 1. Create the domain in Cloud Foundry and associate it with an organization.
  +
  +    The command below defines the custom domain `test.example.org` in the
  +	"test-org" organization:
  +
  +	<pre class="terminal">
  +	$ cf create-domain test-org test.example.org
  +	</pre>
  +
  + 1. Map the route to your app:
  +
  +    <pre class="terminal">
  +	$ cf map-route myapp test.example.org
  +	</pre>
  +
  + 1. Configure your custom domain with your DNS provider using a CNAME record.

  +CNAME records follow the pattern illustrated below:

  In some cases, defining the subdomain portion of a route is optional. In
  generally, though, this segment of a route is required to ensure the route is
  unique.
  Note in particular that you _must_ define a subdomain in the following cases:

  Use a DNS CNAME record to alias a custom subdomain.
  
   1. Create the domain in Cloud Foundry and associate it with an organization.
  
      The command below defines the custom domain `myapp.example.org` in the
  	"test-org" organization:
  
  	<pre class="terminal">
  	$ cf create-domain test-org example.org -n myapp
  	</pre>
  
   1. Map the route to your app:
  
      <pre class="terminal">
      $ cf map-route myapp example.org -n myapp
  	</pre>
  
   1. Configure your custom domain with your DNS provider using a CNAME record.
  
  	CNAME records follow the pattern illustrated below:
