What are CNAME records?

CNAME records are aliases for A records. In other words, you can use a CNAME record to reference an A record. This means that when the IP address of the A record changes, the CNAME also changes automatically.

This is a practical advantage when you refer other websites to the hosting. After all, you only have to change the new IP address in your own A record and not on all other websites that refer to the A record with a CNAME

It is not possible to create a CNAME for the entire domain. This redirection can only be made with a .htaccess file or a forward within your web hosting.
