How to add an external domain to DNS

Reviewed on 31 December 2021Published on 07 June 2021

Scaleway DNS is a managed DNS service that allows you to easily configure the DNS zones of your domains. It provides support for queries via both IPv4 and IPv6 and supports all common types of DNS records.

Scaleway DNS is currently available to manage DNS zones for external domains (ones created at external registrars).

  1. Click DNS in the Network section of the Scaleway Console side menu. The DNS zone dashboard displays. If you have not created a zone yet, the creation page displays:

  2. Enter the external domain name in the box and click the search icon to verify the domain exists. Once verified, the following message displays:

  3. Click Next to validate your domain name. The validation instructions display.

    Add a TXTrecord to the root zone of the domain at your current registrar to validate the domain ownership.


    TXT means text record and it is used to carry machine-readable data such as information for automated domain validation.

    Copy the token displayed and create a TXT record with the name _scaleway-challenge within your current DNS zone as instructed:


    The token’s presence will be checked regularly. If it has not been set within 48 hours, the external domain will be deleted from the service.

  4. Click Manage as External Domain once you have set up the record in your current DNS zone. The list of your external domains displays. The status of any ongoing DNS challenges is visible through blue dot on the left-side of the domain name:

    Once the record has been validated, the dot turns green and you will receive an e-mail with further instructions on how to update your domain's DNS servers.

Update the nameserver information at your current registrar once the domain name is validated in order to link your existing domain name with your Scaleway Domains DNS zone.


Scaleway’s DNS servers are:

  • ns0.dom.scw.cloud
  • ns1.dom.scw.cloud

You can verify if the association of your domain has been successfully completed by checking the Nameservers list in the Domain Information page.


If the entire process is not completed after 14 days, the domains are deleted from the DNS and you will have to start over. E-mails reminding you to complete the process are sent on days 7 and 13.
