What Is CNAME Flattening?

In Plain English

Normally, the root of a domain name (such as yourcompany.com) has limitations on the types of DNS records it can use. CNAME Flattening removes those limitations, allowing root domains to work with modern cloud services and content delivery networks without breaking DNS standards.

Why It Matters

Many website performance and security services—including CDNs and cloud hosting providers—work best with CNAME records. CNAME Flattening allows businesses to take advantage of these services while continuing to use their primary domain name.

What Could Happen Without It?

Without CNAME Flattening, some cloud services may require more complicated DNS configurations or limit how your root domain can be connected.
