  You can modify your application domain by creating parent domains that meet the following requirements:
  
  * **Private Parent Domains**: You can only create a private domain that is parent to a private subdomain.

  If your DNS provider does not support ANAME or ALIAS records, use subdomain redirection, a technique also known as **domain forwarding**, to add a root domain. If you use this method, note that SSL requests to the root domain result in an error because the SSL certificate generally only matches the subdomain.
  
  Configure the redirect from the root domain to the target "www" subdomain, and configure the "www" subdomain as a CNAME record reference to the target app URL. The table below illustrates this pattern.
