Premium DNS
How to protect your website from attacks with Premium DNS
The Gandi Premium DNS service provides a superior level of protection against loss of DNS resolution in the event of an incident on our infrastructure or in the event of a Denial of Service (DDoS) attack. By using this service in addition to our LiveDNS Name Servers, you will benefit from a redundant DNS infrastructure hosted by a third party. You will thus be sure of the availability of your online services (E-mail, Website(s), etc.) in the event of an outage or attack.
IMPORTANT
The Premium DNS service is reserved for our professional customers (based on the owner of the domain concerned) and only for domains using Gandi LiveDNS. The Premium DNS service is not available for domains registered manually through our corporate service. Gandi's Premium DNS service uses Cloudflare's Anycast infrastructure as a redundant backup of our own DNS to mitigate the impact of an outage or attack and keep your digital services online.
Warning
The Premium DNS service works by redirecting traffic to your site through specific Name Servers. If you change your domain's nameservers, the Premium DNS service will be disabled.
How to subscribe to Premium DNS service

Your subscription to this service will be synced with the domain to expire at the same time as your domain name, and the cost will be calculated accordingly. Your site will not be impacted by this operation and will remain online.
How to unsubscribe from Premium DNS service
In the DOMAIN NAME menu, click the domain name.
In the “Name Servers” tab, click “Unsubscribe from Premium DNS” in the Premium DNS section.
After unsubscribing, the pro rata amount of your subscription to this service will be automatically refunded to your prepaid account. If you would like a refund of the prepaid account, please contact support: support-en@support.gandi.net
Why was my Premium DNS service disabled?
The Premium DNS service works by routing queries to your website through specific name servers. In fact, if you configure your domain to use external nameservers; Gandi will no longer be able to provide this service. If you disable the service unintentionally, you can simply re-enable it by following the procedure above.
How can I see all domains currently using the Premium DNS service?
In the list of your Domains, accessible via “DOMAIN NAME” in the navigation on the left, after logging in, the domains for which the service is activated will appear with a “Helm” icon near their name (only in the View advanced). You will be able to see the same helm on the General view of a domain, in the Domain configuration block, and of course under the Name servers tab. You can also filter your domain names in the Advanced View using the filters to only display Domains using this service.
