Secondary DNS: Explained for Beginners

Secondary DNS is a crucial part of any digital infrastructure and provides essential benefits such as improved uptime, faster response times, and added security. In this article, we’ll look at, how to set it up, and some best practices for managing it.

Secondary DNS: What is it?

Secondary DNS is an integral part of any digital infrastructure and one that administrators often overlook. In a nutshell, it provides an added layer of redundancy and failover capabilities to DNS services, providing extra protection against connection and uptime problems associated with the primary DNS services. In addition, this service allows DNS queries to be split across multiple servers, meaning that if one connection fails, the other (secondary) DNS still responds. This ensures more reliable service for your users and can help prevent extended outages or packet loss due to DNS-related issues. This service allows for better redundancy, uptime, and more reliable service than relying on a single DNS server.

Benefits of using it

When it comes to ensuring the safety and reliability of your digital services, Secondary DNS provides many advantages. With it, the DNS requests are split between multiple servers, meaning that if one server fails, the other continues service requests. This dramatically reduces the risk of outages and interruptions due to DNS-related problems. Additionally, this service is highly configurable and can be tailored to your specific requirements and needs. Finally, with Secondary DNS, users can benefit from faster response times. This is because the resources are distributed and load balanced between multiple DNS servers. All these factors make this service a must-have for any business looking to ensure high customer performance and reliability.

So, to sum it up, Secondary DNS brings:

  • Increased redundancy & uptime 
  • Greater flexibility & performance 
  • Faster response times 
  • Added layers of security 
  • Improved scalability

Best Practices for Setting Up and Managing Secondary DNS

Setting up and managing it involves a few different steps and best practices:

  1. It’s crucial to select a reliable DNS provider with a good history of uptime and security. Once the provider is chosen, the next step is configuring the primary and Secondary DNS servers to ensure that they are configured correctly. This includes setting up the correct TTL values, testing the configuration before going live, and keeping the server up to date.
  2. It’s essential to regularly monitor the Secondary DNS for any potential issues, such as latency or packet loss, and to ensure the records are not being cached incorrectly.
  3. It’s also essential to ensure that the DNS records stay accurate, and that any changes made to the DNS records are propagated correctly.

In summary, setting up and managing this service requires careful attention and monitoring but is worth it for its added protection and reliability.

Secondary DNS providers

Finding the right Secondary DNS provider is vital to ensuring the reliability and stability of your digital infrastructure. The best providers will have a good history of providing stable, secure services and will offer various features to suit your needs. Look for providers that provide redundant DNS hosting, a global presence, fully managed DNS services, Anycast DNS, Monitoring services, and reliable DDoS protection. Additionally, it’s essential to select a provider with a support team that is both knowledgeable and available to help in case of any issues or cyber vulnerability. Ultimately, the best providers will provide various features and ensure that your services are always online and secure.


Secondary DNS is a powerful way to protect your digital infrastructure from outages and other issues and offers various features and benefits. Investing the time and energy in setting up and managing it correctly can provide immense peace of mind and ensure reliable, secure services.
