DNS Zone

• a common mistake is to associate a DNS Zone with a domain name or a single DNS server
• a DNS Zone can contain multiple subdomains and multiple zones can exist on the same server

DNS Zone Example

imagine a hypothetical zone for the cloudflare.com domain and three of its subdomains: support.cloudflare.com, community.cloudflare.com, and blog.cloudflare.com. Suppose the blog is a robust, independent site that needs separate administration, but the support and community pages are more closely associated with cloudflare.com and can be managed in the same zone as the primary domain. In this case, cloudflare.com as well as the support and community sites would all be in one zone, while blog.cloudflare.com would exist in its own zone
