Objective

If you are configuring your VPS as a DNS server, you can make use of the OVHcloud Secondary DNS service to host a secondary zone. This way, DNS for your domain will remain available even if the primary DNS server should become unresponsive.

This guide explains how to add your domain name in the OVHcloud Control Panel in order to utilise an OVHcloud Secondary DNS server.

Requirements

• A domain name to which you have administrative access
• A Virtual Private Server in your OVHcloud account

OVHcloud Control Panel Access

• Direct link: VPS management

Instructions

Step 1: Retrieving the validation code

Switch to the tab Secondary DNS and click on the button Add a domain.

Enter the domain name you want to add, then click Confirm.

A message will be displayed in your Control Panel regarding the verification process.

It is necessary to confirm your authorisation to manage the domain name before it can be added to OVHcloud Secondary DNS. This is achieved via an automated DNS lookup on the subdomain ownercheck.yourdomainname. An individual string of characters is generated for this purpose and displayed inside the red notification box. Copy this validation code for use in the next step.

Step 2: Verifying authorisation for the domain name

The required action is different, depending on where the DNS of your domain name is managed.

• If the domain name is managed by an external registrar or it uses external DNS servers at this point, log in to the control panel of your DNS provider and add a DNS zone record of the type TXT with the subdomain "ownercheck" and the value provided by executing step 1.

• If the domain is managed by OVHcloud as its registrar and it uses OVHcloud DNS servers, add the TXT record in the Web Cloud section of your OVHcloud Control Panel. You can follow the instructions in our DNS zone guide if you are not familiar with this process.

Step 3: Adding the domain name

As soon as the TXT record is present in the domain name's DNS zone, repeat the steps described in the first part of this guide to add the domain name to the OVHcloud Secondary DNS server.

Clicking on Confirm will trigger the automatic owner verification by querying the TXT record. A message in your Control Panel will confirm the successful DNS check. You can now delete the TXT record.

Added domain names will be listed in this tab with the corresponding name of the secondary DNS server. (Refresh the page in your browser after adding a domain name.)

Domain names can be removed by clicking on the ... button in the table.
