What types of records are typically stored by DNS servers?

DNS servers are responsible for translating human-readable domain names into IP addresses and managing mapping records for various services associated with a domain. The correct answer highlights several types of records that DNS servers typically handle.

IP addresses are stored in A records, which map domain names to IPv4 addresses, and in AAAA records, which do the same for IPv6 addresses. MX records are important for email routing and indicate the mail exchange servers for the domain. NS records specify the name servers for the domain, which are essential for delegated domains. CNAME records allow multiple domain names to point to a single canonical domain name, facilitating easier management of domain names.

This combination of records (IP addresses, MX records, NS records, and CNAME records) reflects the variety of functions DNS serves, making this response accurate and comprehensive. Each type of record plays a crucial role in ensuring that domain name resolution and resource management over the Internet are performed efficiently.
