What are DNS records and how does domain name resolution work?
The Domain Name System (DNS) acts as the phonebook of the Internet, translating human-friendly domain names (such as google.com) into numeric IP addresses used by servers to route traffic.
Guide to Core DNS Record Types
- A & AAAA: Route a domain to 32-bit IPv4 and 128-bit IPv6 host addresses.
- MX (Mail Exchanger): Designate the mail servers responsible for accepting incoming emails with priority levels.
- TXT (SPF, DKIM, DMARC): Stores text records for email authentication (SPF, DKIM, DMARC) and site ownership tokens.
- CNAME & NS: Define aliases pointing to other hostnames and delegate zone authority to Name Servers.
WHOIS & Email Authentication
RDAP (Registration Data Access Protocol) is the modern ICANN standard replacing legacy port-43 WHOIS with secure, structured JSON responses for domain registrar details, expiration dates, and nameservers.
