What DNS record maps a domain name to an IPv4 address?

Explanation:
DNS translates a domain name into its network address. To map a domain to an IPv4 address, you use the A record, which stores the IPv4 address directly so the resolver can return it when queried. AAAA records serve the same purpose but for IPv6 addresses. MX records designate mail servers, and CNAME records create an alias to another domain name (which then resolves to an A or AAAA record). So for IPv4 mapping, the A record is the one you use.
