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 a very easy and friendly way. It supplies you with an additional set of Authoritative DNS servers that can respond to incoming requests for your domain name. You can manage the DNS records of the domain name only at a single (Primary DNS) provider and the second provider using the Secondary DNS technology can be kept up to date and synchronized automatically.
Every domain name requires a Primary DNS server to hold all of the available resource records for each precise domain and respond to DNS queries for it. However, for fast loading time, improved load balancing, and redundancy if a DNS outage or malicious attack occurs, many domain owners trust Secondary DNS.

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

The Secondary DNS can be used as a 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 your own DNS servers, you can secure them with Secondary DNS configuration with hidden Master. ClouDNS will handle all the public traffic for you.

Improved performance

Secondary DNS can improve the performance of your website by distributing the traffic across multiple servers.

Easy migration

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.
