CNAME Record

A CNAME (Canonical Name) record is an alias that points one domain or subdomain to another domain.

In plain English

An alias: “when someone goes to blog.mysite.com, send them to the same place as myotherservice.com.” Handy when the real address might change.

Instead of pointing to an IP address, a CNAME record points to another domain name. For example, you might point `blog.example.com` to `example.host.io`. This is useful when your underlying service address might change, as you only have to update the final destination in one place.

A CNAME record cannot coexist with other records for the same name (like an MX record for the apex domain), which is why ALIAS records or A records are used for root domains.
