A DNS record that makes one domain name or subdomain point to another hostname instead of pointing directly to an IP address. It is commonly used for addresses such as www, shop, or app, and it is also used when connecting a subdomain to an outside service that gives instructions using a hostname.
How CNAME Record Works
A CNAME Record points one domain name or subdomain to another hostname rather than directly to an IP address. It is often used when a service provider wants a subdomain to follow a destination that the provider may manage or change.
Simple Example
You point tools.example.com to a hostname supplied by a software provider using a CNAME.
Why It Matters for Beginners
This matters because many hosted tools require a CNAME when connecting branded subdomains. Knowing that it points to another hostname helps prevent accidental DNS changes elsewhere.
A Common Mistake
Replacing an unrelated DNS record because the hostname looks similar.
