Which are common service records stored in DNS?

The answer identifies a selection of widely used DNS records that play essential roles in domain name resolution and handling various types of network traffic.

Starting with the A record, it maps a domain name to an IPv4 address, which is fundamental for enabling access to a server via its domain name rather than its numeric IP address. The AAAA record serves a similar function but is specifically for mapping domain names to IPv6 addresses, catering to the modern need for expanded IP address allocation.

A CNAME record allows one domain name to be an alias for another domain name. This is particularly useful for managing multiple services or hosting scenarios under a single domain without needing to create additional A records.

Finally, the MX record is crucial for email delivery, as it specifies the mail servers responsible for receiving email on behalf of a domain. Proper configuration of MX records is essential to ensure reliable email communication.

Each of these records serves distinct yet critical functions within the DNS framework, making them among the most commonly utilized DNS service records.
