Editing an OVHcloud DNS zone

Objective

DNS means Domain Name System and is a set of elements (DNS servers, DNS zones, etc.) that map a domain name to an IP address.

For further explanation, please refer to our guides “Everything you need to know about DNS servers” and “Everything you need to know about DNS zone”

This guide explains how to edit your OVHcloud DNS zone via the OVHcloud Control Panel.

Requirements

OVHcloud DNS servers in use for the domain name concerned

OVHcloud Control Panel Access

Direct link: DNS zones
Navigation path: Web Cloud > DNS zones > Select your domain name

Warning

If your domain name does not use OVHcloud DNS servers, you will need to edit the configuration using the interface of your service provider that manages your domain name.
If your domain name is registered with OVHcloud, you can check if it uses our configuration. If needed, refer to our guide on Modifying the DNS servers for an OVHcloud domain name.

In both of the above cases, be careful when making your DNS server changes. The old configuration that can be applied to your domain name will no longer be active if you have not previously reconfigured and customised the new DNS zone present at OVHcloud. You can only have one active DNS zone per domain name at a time.

Instructions

Access the area for managing an OVHcloud DNS zone

Info

Unlike domain names, a DNS zone has no "holder", but is managed at OVHcloud through the contact management. If you wish to assign the management of your DNS zone to another OVHcloud customer account, follow our guide Managing contacts for your services.

Step 1

Step 2

Go to the DNS zones page, then choose the domain name concerned.

Edit your domain name’s OVHcloud DNS zone

Editing a DNS zone is a sensitive procedure: An inappropriate change could, for example, make your website unavailable, or prevent your email addresses from receiving new emails.

By learning more about these records, you can get a better understanding of the changes you will make if you edit your domain name’s DNS zone.

Tip

Read our guide on DNS records to get a better understanding of your DNS changes.

See also our guide to subdomains for more information on this topic.

You can edit your domain name’s OVHcloud DNS zone by adding, modifying, or deleting a DNS record. To do this, you can either manually edit the zone in text mode, or use our configuration assistants.

Manually edit the zone in text mode

Warning

For informed users only. Be careful with syntax when you make changes.

To edit an OVHcloud DNS zone in text mode, click on the tabs below to view each of the 2 steps.

Step 1

Step 2

Go to the DNS zones page, then choose the domain name concerned.

Use our configuration assistants

From this point onwards, this guide will only cover configuration using our configuration assistants.

Info

In order to modify your OVHcloud DNS zone successfully, make sure to gather all the required information first. If you are making this change at the request of a service provider, the service provider must provide you with a list of the items to change.

Click on the four headings below to see the explanations.

Add a new DNS record

To add a new DNS record, click on the tabs below to view each of the 2 steps.

Step 1

Step 2

Go to the DNS zones page, then choose the domain name concerned.

On the right or below the table, click Add an entry, then follow the steps that appear.

We recommend that you check beforehand if this record exists and already points to a different target. To do this, filter the contents of the table by record type or domain. If the record exists, modify it using the steps described below.

When the target of your record is a URL, remember to punctuate it. If you do not do this, your domain name will be automatically added to the end of your target. Example: You want to create a CNAME record from test.mydomain.ovh to mydomain.ovh. You must then have as target mydomain.ovh. and not mydomain.ovh without the . at the end.

Reset the DNS zone

By resetting your DNS zone, you can revert back to a minimal configuration, with OVHcloud default records, or your services’ records. You can also point your domain name to custom web hosting and email services.

Danger

Before you reset your DNS zone, ensure that your domain name is not attached to services that are in use, such as a website or email addresses.

Step 3

Step 4

Go to the DNS zones page, then choose the domain name concerned.

Whichever option you choose in the previous step, you will need to set values for queries to your domain name to prevent an incorrect DNS response.

Click on the tabs below to view the details of the available options.

Web hosting plan IP address

Redirection: Your domain name will point to the OVHcloud redirection server, which can be used to display an OVHcloud homepage, and thus avoid a DNS error.
OVHcloud web hosting: Your domain name will point to the IP address of the Web Hosting plan associated with the domain name.
Custom: Enter the IPv4 address (A record) of the Web Hosting plan you want to point to.

Mail server address

Redirection: Your domain name will point to the email redirection servers. This is particularly useful if you do not have any email solutions, but would like to send emails to one or more email addresses outside of your domain name.
OVHcloud email server: To be defined if you have a shared email solution.
Custom: Enter the URL and priority of the email server (MX record) you want to point to.

Propagation time

Once you have modified your domain name’s DNS zone, you will need to allow a maximum of 24 hours for the changes to propagate fully, and be effective.

If you would like to reduce this delay for the next edits of your OVHcloud DNS zone, you can do so to a certain extent by adjusting the TTL (Time To Live), which will apply to all of the records in the DNS zone. To do that, click on the tabs below to view each of the 2 steps.

Step 1

Step 2

Go to the DNS zones page, then choose the domain name concerned.
