Cloudflare Allows CNAME For Apex Domain
If you want to set up a custom root (apex) domain with an app hosting provider
like
Heroku,
you're going to need to work with a DNS provider that supports the non-standard
ALIAS records (or something equivalent).
In my case, I have my domain registered with Cloudflare. Cloudflare supports this kind of CNAME lookup of an apex domain through CNAME flattening.
Unlike other registrars that use a separate ALIAS record concept, Cloudflare
allows you to set up a specialized CNAME record. Go into the DNS settings for
the domain of interest, click "Add Record", and then select CNAME. From there,
instead of entering a traditional subdomain like www, you put the @ symbol
which tells Cloudflare that this is a record for the apex domain. That record
will still point to a target like abc123.herokudns.com as a more traditional
CANME would do.
