How to configure the reverse DNS of a failover IP

Reviewed on 02 October 2023Published on 13 April 2022

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.

Security & Identity (IAM)

To perform certain actions described below, you must either be the Owner of the Organization in which the actions will be performed, or an IAM user with the necessary permissions.

  • You have an account and are logged into the Dedibox console
  • You have performed the linking process between Dedibox and Scaleway
  • You have ordered a Dedibox server
  • You have ordered a failover IP

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

  1. Click Dedibox in the Bare Metal section of the side menu.

  2. Click the Failover IPs tab to display a list of your failover IPs.

  3. Click «See more Icon» next to the failover IP you want to edit. A drop-down menu displays.

  4. Click Edit reverse. A pop-up displays.


    You can click «See more Icon» next to the IP you want to configure in the listing of the failover IPs in the left.

  5. Enter a new IPv4 reverse DNS and click Save changes.


    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.
