CNAME

CNAME stands for Canonical Name record. It is a type of DNS record used to associate one domain name with another domain name.

In other words, a CNAME record allows a domain name to act as an alias for another domain name. When a user enters the alias domain name in their web browser, the DNS system looks up the corresponding canonical domain name associated with the CNAME record, and then resolves the IP address for that canonical domain name.
