If you don't have that, start here: How do I expose my web app on the Internet?.
As noted in the Custom Domain documentation, Aptible requires that you create a CNAME from the domain of your choice to the Endpoint Hostname.
Unfortunately, DNS does not allow the creation of CNAMEs for domain apexes (also known as "bare domains" or "root domains").
Regardless of the approach you choose, you'll need a provider that supports ALIAS records (also known as CNAME flattening), such as Amazon Route 53, Cloudflare, or DNSimple.
If your DNS records are hosted somewhere else, you will need to migrate to one of these providers or use a different solution (we very strongly recommend against doing that).
Note that you only need to update the NS records for your domain (in other words: you can keep using your existing provider as a registrar, and you don't need to transfer the domain over to one of the providers we recommend).
