Which server type utilizes record types such as A, NS, AAAA, and MX?

A DNS server is responsible for translating domain names into IP addresses and vice versa. It uses various record types to store and manage information related to domain names. The record types mentioned—A, NS, AAAA, and MX—each serve specific purposes within the DNS system.

The A record maps a domain name to its corresponding IPv4 address, allowing users to access websites using easy-to-remember domain names instead of numeric IP addresses. The AAAA record performs a similar function but maps domain names to their IPv6 addresses, which are increasingly important as the number of devices connected to the internet continues to grow. The NS (Name Server) record indicates which DNS servers are authoritative for a particular domain, playing a critical role in the delegation of domain name resolution responsibilities. The MX (Mail Exchange) record specifies the mail servers responsible for receiving email on behalf of a domain, directing email traffic correctly.

Understanding these record types is essential for comprehending how domain resolution works, where the DNS server acts as a translator between human-readable domain names and machine-readable addresses. This makes the DNS server the correct answer, as it is specifically designed to handle these types of records and functionalities.
