CNAME records make your DNS data easier to manage. If you change the IP address of an A record, all CNAME records pointed to that A record automatically follow the new IP address. The alternative solution, multiple A records, is not as simple as using CNAME records.

A CNAME (Alias) record points to an A (Host) record. You can create multiple CNAME records and point them to an A record. The most common CNAME records are the subdomains www and ftp.

 Note: If your domain is registered at another company, see the Domains registered at another company section below for instructions.
