A primary DNS nameserver is the authoritative DNS server that maintains domain records and other important information. It is without this server that users cannot access the internet or find websites.
The DNS resolver converts domain names into IP addresses that are easy for machines to understand. The resolver will then send this request to an authoritative DNS server which will provide the correct IP address.
It is vital that the primary DNS servers function properly. Any business or organization seeking to protect their presence online should take this into consideration. But they are vulnerable to various problems such as power outages and cyber attacks, or even maintenance issues.
Secondary DNS allows for a network to manage load more efficiently and improve DNS performance. 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 enables businesses and organisations to remain available to their customers even if the primary DNS fails. It also allows them to maintain their brand online.
A secondary DNS server can be configured on a network in the same way as a primary DNS server. The secondary DNS server has the identical functionality, uses the IP addresses and can provide backups to the primary DNS if necessary.
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. A secondary DNS provider can also help to keep the IP addresses of your domains automatically updated.
What is primary dns?
The main role of a primary DNS server is to hold an authoritative copy of the DNS zone file for a domain, or a hostname. This copy contains all the DNS records that are associated with the domain. It is crucial for determining the destination of web pages when you search for them.
This is the same information that a recursive resolver needs to send users to their desired destinations. It will also ask for this information from a second DNS server if the DNS recursive resolution is not available or is slow in responding.
A secondary server can copy the zone data of a primary server, using a procedure called zone transfer. A secondary server can then serve this data to clients - ensuring that your business or organization is able to continue functioning in the event of an outage on the primary DNS server.
It is important to have a second server in order to make sure that DNS changes are made correctly. This is especially important when a DNS server's IP address changes, for example due to network problems or other issues.

What platform is the best to design a site?
WordPress is the best platform when it comes to designing websites. It has all the features required to create a professional-looking website.
Themes are easy to install and customize. You have thousands of options for free themes.
You can also add functionality by installing plugins that allow you to do everything from adding social media buttons to adding forms and contact pages.
WordPress is easy to use. To change your theme files you don't need HTML code. All you need to do is click on an icon and select what you want to change.
Although there are many platforms out there, I prefer WordPress. It's been around since the beginning and is still being used by millions of people worldwide.
