What does Private DNS server mean?

Today we will explore the Private DNS server. This is one really important component for your network business security. But first, let’s explain what DNS server means.

DNS server: What does it imply?

To start explaining what a Private DNS server is, let’s see what does DNS (Domain Name System) server means briefly. In 1983 it was created, and 3 years later, it became one of the original Internet Standards. It is a part of the DNS resolution process. That means it helps to translate human-friendly URLs into computer-friendly IP addresses. So, it turns to and vice versa.

Private DNS server: Complete explanation

A Private DNS server is something unique and special, as the name suggests. They are DNS networks that do not belong to the widespread DNS infrastructure. Imagine it as a modest personal library with a few books in it. This has advantages and disadvantages. However, you won’t be able to read any books from a specific genre. On the other hand, there is one benefit: since your library is private, nobody will know what you are reading.

How beneficial is it?

A private DNS server offers a ton of advantages. We’ll simply look at one aspect of them. These are what they are:

  • You feel more secure as a result! This is almost certainly the Private DNS server’s most crucial advantage. Using a public DNS server can make you more susceptible to DoS and DDoS attacks. However, this is extremely unlikely to occur if you use a Private Domain Name System server.
  • Additional DNS records and zones. As many DNS zones and DNS records as your server can accommodate will be supported. In other words, you will have access to all the DNS records you require (A, AAA, SOA, PTR, MX, TXT, CNAME, etc.).
  • Possesses nearly all premium services. Yes, almost all premium features are present on the Private Domain Name System server. It might, for instance, include both Secondary DNS and Dynamic DNS (DDNS).

What does a Public DNS server mean?

A user’s Internet Service Provider (ISP) assigns them a default DNS server when they register for an Internet account. Most ISPs have their own DNS servers. Additionally, new users typically don’t have to worry about those servers’ configurations.

But occasionally, if the ISP‘s DNS servers are sluggish, the user could want to use DNS servers from a different service provider.

Utilizing public DNS servers is the answer. The most popular ones are, for example, Google (IPv4 –, Quad9 (IPv4 –, Cloudflare (IPv4 –, etc.


Let’s go over everything again. First and foremost, a Private DNS server is hugely beneficial. It contributes to increased security. Furthermore, it adds more DNS zones and records. As a result, businesses would benefit from implementing a Private DNS. Its employees are secure, and criminals will be unable to “probe” or “scout” their network or communications. Furthermore, private DNS can operate with little or no management once properly configured. Having it implemented is therefore worthwhile.
