What Is DNS? Definition & Guide

DNS (Domain Name System) is the system that translates readable domain names (like carbonstealth.eu) into the numeric IP addresses of servers, letting the browser find the right site.

How DNS works

DNS is like the internet's phone book: you type a name, it finds the number. When you enter an address, the browser queries DNS servers to learn which server hosts that domain, then loads the site. It all happens in milliseconds. DNS records (A, CNAME, MX, TXT) tell where the site, mail and other services point.

What DNS records are for

• A record: links the domain to the IP of the hosting server.
• MX record: routes email to the mail server.
• CNAME record: creates aliases, useful with a CDN or subdomains.

Why DNS matters

A correct DNS setup keeps the site and email working and affects resolution speed. Changes can take a few hours to propagate worldwide. In our hosting service we manage DNS for you, avoiding errors that would take the site offline.
