+# Cloudflare Allows CNAME For Apex Domain
+
+If you want to set up a custom root (apex) domain with an app hosting provider
+[like
+Heroku](https://devcenter.heroku.com/articles/custom-domains#add-a-custom-root-domain),
+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_](https://developers.cloudflare.com/dns/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.
