Managing a DNS zone's history
Objective
The Domain Name System (DNS) zone of a domain name is its configuration file. It is made up of technical information, called DNS records. The DNS zone is, in a way, like a switching centre.
For more information, please refer to the following guides:
- Everything you need to know about DNS servers
- Everything you need to know about DNS zones
- Everything you need to know about DNS records
For various reasons, you may need to apply an older DNS configuration to your domain name.
DNS management is now made easier thanks to the history of your DNS zones.
Find out how to view, compare, download and restore your DNS zone backups.

The following window appears.

Check that the date shown in the message corresponds to the DNS zone you want to restore. As the yellow banner indicates, remember that the current DNS zone (at the top of the DNS zone history list) will be deleted and replaced by the DNS zone you want to restore.
Click Restore to confirm the restoration, or Cancel.

On the right, content highlighted in green has been modified or added compared to the older version.
