Do you have a root mapping record?

Yes. Nice work!

You have 1 root CNAME record: dnsdigest.fly.dev.

Note: Technically, CNAME records can't be used at the root of a domain (e.g. dnsdigest.com) because it conflicts with other essential DNS records like SOA (Start of Authority) and NS (Name Server) records. However, some DNS providers allow you to create root CNAME records which resolve the CNAME target to the appropriate A or AAAA record. This is called CNAME flattening.

Why is this important?

A root mapping record (usually a A or AAAA record) is one that doesn't have a hostname like www associated to it. It's important because it tells the internet where your website or service is located.

The root record ensures that when someone types dnsdigest.com in a browser without www, for instance, they can still get to your site.
