Which DNS record type is specifically used to map a fully qualified domain name (FQDN) to its corresponding 32-bit IPv4 address, enabling devices to locate the correct host on an IPv4 network?
A record
MX record
AAAA record
CNAME record
The Address (A) record is the fundamental DNS record used to associate a domain name with a 32-bit IPv4 address. This mapping allows a resolver to translate human-readable names into the numeric IPv4 addresses required for routing traffic on an IPv4 network. The AAAA record performs the same function for IPv6 addresses, CNAME creates an alias that points one name to another canonical name, and MX specifies mail-exchange servers for a domain.
