How to configure the reverse DNS of a flexible IP on Bare Metal servers

Reviewed on 26 May 2021Published on 26 May 2021

Reverse DNS, or rDNS, is exactly the opposite of classic forward DNS as we know it. Forward DNS maps a hostname to an IP address. Reverse DNS means we are mapping the IP address to a hostname. This can be very useful, especially if you want to send emails from your Bare Metal server.

  1. Click Bare Metal in the Compute section of the Scaleway Console side menu. The Bare Metal dashboard displays.

  2. Click the Flexible IPs tab.

  3. Click «See more Icon» next to the flexible IP that you want configure. The configuration menu of the flexible IP displays.

  4. Click More Info to see detailed information about the IP address.

  5. Scroll down to the Reverse section and click on Add Reverse:

  6. Enter the new reverse DNS and click Edit this reverse to validate the changes.


Make sure that a corresponding A-Record pointing to the IP address exists before editing the reverse DNS of an IP address.
