A record AND CNAME

The A record points a name to a specific IP.

The CNAME record points a name to another name instead of to an IP. The CNAME source represents an alias for the target name and inherits its entire resolution chain.

The A record maps a name to one or more IP addresses when the IP are known and stable. The CNAME record maps a name to another name. It should only be used when there are no other records on that name. The ALIAS record maps a name to another name, but can coexist with other records on that name.
