How DNS Works

🌍

Root Servers

At the top of the DNS hierarchy, 13 root server groups are distributed worldwide. They direct queries to TLD servers.

🏢

TLD Servers

Top-Level Domain servers (.com, .org, .net, etc.) hold information about authoritative servers for domains under their extension.

🎯

Authoritative Servers

Each domain has its own authoritative nameservers that hold the actual DNS records (A, MX, TXT, etc.).

📝

A Record

Address Record - Maps a domain name to an IPv4 address. The most fundamental DNS record type.

📧

MX Record

Mail Exchange - Defines mail servers for the domain. Priority values determine which server is tried first.

🔗

CNAME Record

Canonical Name - Creates an alias pointing to another domain name. Useful for subdomains.
