What is a DNS A record?
An A record maps a hostname directly to an IPv4 address.
The short version
An A record maps a hostname directly to an IPv4 address. It is the most basic DNS record, and it works at the root of a domain, where a CNAME is not allowed. If the server's address changes, you need to update the record by hand, so prefer a CNAME where you can.
