How to configure the reverse DNS of a failover IP on Dedibox

Reviewed on April 30, 2025

Note

Only users who have completed the linking of their the Dedibox account to the Scaleway console are granted access to the Dedibox section within the Scaleway console. For detailed information on the migration process, please refer to our account linking documentation. If you cannot locate the Dedibox link in Scaleway's console side menu, you can use the Dedibox console to place orders, manage your Dediboxes, and access the related documentation.

You can edit the reverse DNS of a failover IP address to a custom value. This can be useful when you want to send emails from your Dedibox, as certain remote mail servers do not accept emails coming from generic reverse hostnames.

Before you start

To complete the actions presented below, you must have:

A Dedibox account logged into the console
Owner status or IAM permissions allowing you to perform actions in the intended Organization
Linked your Dedibox and Scaleway accounts
Ordered a Dedibox server and a failover IP

Click Dedibox in the Bare Metal section of the side menu.
Click the Failover IPs tab to display a list of your failover IPs.
Click more icon next to the failover IP you want to edit. A drop-down menu displays.
Click Edit reverse. A pop-up displays.

Tip
You can click more icon next to the IP you want to configure in the listing of the failover IPs on the left.
Enter a new IPv4 reverse DNS and click Save changes.

Important
Make sure that a valid and corresponding A-Record is set for the reverse DNS you want to configure.

The reverse DNS (PTR-Record) of the failover IP is being updated.
