@ is invalid hostname DO DNS Cname record.

I’m trying to direct my main site URL to a CDN where the files are stored. My backend is in a droplet so I’m using DO DNS. The problem is it doesn’t allow me to use @ as a hostname in the cname record to redirect my domain to the cdn, keeping my subdomain on DO.

Any ideas?

A CNAME record defines an alias for an A record; it points one domain to another domain instead of to an IP address. When the associated A record’s IP address changes, the CNAME will follow to the new address.

  • The apex domain (@). To map a apex domain, like, enter the @ symbol.
  • A subdomain (e.g.
