Secondary DNS

What is Secondary DNS?

The Secondary DNS provides a way to distribute the DNS traffic for a domain name to two or more DNS providers for the best possible uptime and redundancy in very easy and friendly way. You can manage the DNS records of the domain name only at single (Primary DNS) provider and the second provider using the Secondary DNS technology can be kept up to date and synchronized automatically.

Benefits from using Secondary DNS service

Some of the main benefits of setting a Secondary DNS include:

• 100% Uptime: If the Primary DNS provider becomes unavailable, the DNS traffic will automatically be served by the secondary provider without any visible effects to the visitors of the web site.
• Backup DNS: The Secondary DNS can be used as backup plan, if something happens with the primary provider. You will have a fresh copy of all your DNS records.
• Provider independency: Last few years the DDoS attacks are growing in both frequency and severity. Adding additional DNS provider with Secondary DNS gives you better security and provider independency.
• Additional security: If you manage own DNS servers, you can secure them with Secondary DNS configuration with hidden Master. ClouDNS will handle all the public traffic for you.
• Easy migration from self hosted DNS to Managed Anycast DNS: If you manage your own DNS servers, adding Secondary DNS is a fairly easy process. You can migrate to DDoS Protected and Anycast DNS transparently without any other changes of your management system, access and control panels.
