A Canonical Name or CNAME record is a type of DNS record that maps an alias name to a true or canonicaldomain name. CNAME records are typically used to map a subdomain such as www or mail to the domain hosting that subdomain’s content. For example, a CNAME record can map the web address www.example.com to the actual web site for the domain example.com.

When using Google Cloud services, you might need to add a CNAME record to your domain’s DNS settings to customize a web address, verify domain ownership, or reset your administrator password. See below to learn more and add CNAME records now.
