What is DNS?

DNS (Domain Name System) translates human-readable domain names (like google.com) into IP addresses (like 142.250.80.46) that computers use to identify each other on the network.

A vs AAAA Records

A records map domains to IPv4 addresses (32-bit). AAAA records map to IPv6 addresses (128-bit). Modern websites should have both for universal accessibility.

MX Records Explained

MX (Mail Exchange) records specify mail servers responsible for accepting email messages on behalf of a domain. The lower the priority number, the higher the preference.

TXT Records & SPF

TXT records contain text information for external sources. They’re commonly used for SPF (Sender Policy Framework) to prevent email spoofing and domain verification.
