Definition

The DNS (or Domain Name System) translates a domain name into an IP address (the actual location of your website), so that your requests can reach the target server.

The difference between DNS servers and DNS zones

DNS servers

  • DNS servers are the servers which have been assigned to a domain name. It is therefore these servers which respond first before handing over to the DNS zone.

DNS zone

-The DNS zone is a file that stores different records which refer to, among other things, the addresses of the servers hosting your website (A), or your emails (MX). These addresses can take the form of IP addresses or host names.

Why should I edit servers or the DNS zone?

DNS servers

You may need to change DNS servers when switching registrar. Indeed, some registrars do not allow you to continue using their servers after you have switched your domain name to a competitor . You might also have your own dedicated server which uses a DNS server, and you want to use this to manage your domain .

DNS Zone

When you want to change the server that hosts your website or your email. For example you may have changed host and need to modify your DNS zone. Once this has been updated, your domain will point to the new servers.
