Exploring the Importance of Secondary DNS Service

Organizations often employ Secondary DNS to maintain uninterrupted service, a valuable strategy for enhancing DNS reliability. In today’s article, we’ll explore what it is, why it’s important, and how it can benefit your online operations.

What is Secondary DNS?

You’re probably familiar with the fact that Primary DNS servers play a pivotal role in resolving domain names to IP addresses. However, these servers are not immune to downtime, hardware failures, or network issues. So, here comes Secondary DNS, which serves as a backup to primary DNS, offering redundancy and resiliency to ensure that domain name resolution continues to function even if the primary server experiences problems.

In a typical setup, a secondary server replicates and stores DNS zone data from the primary DNS server. When a DNS query is made, the backup server can respond with the same information as the primary, effectively serving as a failsafe mechanism. If the primary DNS server is inaccessible or experiencing issues, the backup DNS server can step in and continue resolving domain names, preventing service disruptions.

Why it is Important?

Here are several reasons why implementing backup DNS is so crucial:

  • Enhanced Reliability: The primary goal of secondary DNS is to provide redundancy. It ensures that your website or online service remains accessible even when the primary DNS server encounters problems. This resilience minimizes downtime, which is crucial for businesses where every minute of unavailability can result in lost revenue and damaged reputation.
  • Load Distribution: Backup DNS can also help distribute the query load across multiple servers. By spreading the DNS queries between the primary and secondary servers it helps prevent overloading the primary server during traffic spikes, ensuring that users experience consistently fast response times.
  • Geographical Redundancy: Backup DNS can also offer geographical redundancy. By deploying backup servers in different geographical locations, you can further enhance your website’s availability and speed for users worldwide. This approach helps mitigate the impact of localized outages or network issues.
  • DDoS Mitigation: It can be part of a broader DDoS mitigation strategy. In the event of a DDoS attack on your primary DNS server, a backup server can help absorb some of the attack traffic, reducing the risk of service disruption.
  • Maintenance and Updates: Backup DNS servers can be useful for making planned changes or updates to your DNS configuration. You can first update the secondary server, test it, and ensure everything is working correctly before applying changes to the primary server. This minimizes the risk of configuration errors impacting your primary DNS.

Implementing Secondary DNS

Implementing secondary DNS involves configuring a backup DNS server to replicate the zone data from the primary server. This process typically involves the following steps:

  • Choose a Secondary DNS Provider: You can opt for a secondary DNS service provider or set up your secondary server. Many organizations prefer using third-party providers because they offer specialized infrastructure and expertise in DNS management.
  • Configuration: Configure your primary DNS server to allow zone transfers to the secondary server. This typically involves setting up access controls and defining the secondary server’s IP address.
  • Synchronization: The backup server periodically synchronizes with the primary server to obtain the latest DNS zone data. This ensures that it always has up-to-date information.
  • Monitoring: Regularly monitor the status and performance of both your primary and backup DNS servers to ensure they are functioning correctly.


Secondary DNS is an essential tool for organizations and individuals looking to enhance the resilience and reliability of their online services. By providing redundancy, load distribution, and geographical diversity, secondary DNS helps mitigate the risk of DNS-related downtime. Implementing backup DNS can help you achieve that goal and provide a better online experience for your users.
