A primary DNS server is the authoritative nameserver that holds a domain's records and important information. Without this server, users couldn't access the internet and find websites.
When you enter a domain into your browser, a DNS resolver will translate it into an easy-to-understand IP address for machines. The resolver will then send this request to an authoritative DNS server which will provide the correct IP address.
They are essential to the operation of the entire DNS System, so keeping them secure is an important consideration for any company or organization that wishes to protect its presence online. However, they can be vulnerable to a variety of problems, such as maintenance issues, power outages, cyberattacks, and hardware failures.
Secondary DNS (SDN) is a service that enables a network to distribute load and improve the performance of DNS operations. It reduces stress on the primary DNS server and can ensure that requests for a specific domain are handled by another server, regardless of whether the first one is available or not.
It ensures that the website will continue to receive traffic, even if its primary DNS server doesn't respond. This redundancy allows businesses and organizations to remain accessible to their customers in the event of a failure on the primary DNS server, and to maintain their brand image online.
On a network, a secondary DNS server is configured in the same manner as a primary server. It can be configured to have the same functionality and use the same IP address as a primary DNS server.
A secondary DNS server is a great way to ensure that DNS services always work. This can be very useful for businesses or organizations with a global presence. In addition, having a secondary DNS provider in place can help keep your domains' IP addresses automatically updated.
What is primary dns?
The primary DNS server has the main responsibility of holding an authoritative version of the DNS Zone File for a specific domain or hostname. This copy contains the DNS records of the domain, and it is vital to determine where to send the web pages you request.
This is also the information that a resolver recursive needs to send users on their way. When the DNS resolver takes a long time to respond or is unavailable, it asks for a backup copy on a secondary DNS Server.
A secondary server can copy the zone data of a primary server, using a procedure called zone transfer. A secondary server will then be able to serve the data to the clients, ensuring that you or your organization can continue operating in the case of a primary DNS server outage.
A secondary server is essential to ensure that changes are reflected correctly. The primary server only has the ability to change DNS records for the domain. This is particularly true if a primary DNS changes its IP address due to network issues or other problems on the primary DNS server.
