DNS (Domain Name System) translates an easily-memorized domain name into an IP address, allowing the Internet to work. Reverse DNS simply maps the IP address back to the domain name. In this article, we will be showing you how to configure reverse DNS in the OVHcloud Manager.

Configuring Reverse DNS on an IP
To configure reverse DNS on an individual IP address, log in to the OVHcloud Manager, then click the IP option in the left-hand column of the page.
Select the ellipses (...) button to the right of an IP. Then, click the Modify the reverse option from the drop-down menu.
In the following window, enter the domain name corresponding with the IP address it points to in your A-record and click the Confirm button to save the changes.
If the change is successfully made, you are all done. If the change is unsuccessful, check your A-record with your DNS host to ensure that the record is properly configured.
