The Domain Name System (DNS) is the internet's directory. It turns your readable domain name into a numeric address that a server understands.
The idea in short
When a visitor types your domain name into the browser, their device asks DNS for the real address of the server that hosts your project, and DNS points them to the right place within a fraction of a second.
Why it is worth understanding
- It is what really connects your domain name to your project's server.
- A mistake in its records can make the website unavailable.
- It controls where email and subdomains go.
- Its records are managed entirely from the control panel.
