DNS zone: 4 Types You Should Know

Today we will talk about the DNS zone. First, we will explore its purpose and then its different types. Finally, we will explain how you can locate your DNS zone. Let’s start!

DNS zone description

A DNS (Domain Name System) zone is a database containing Resource Records from a single DNS Namespace. Another way to say it, these zones are designed to make administration simple and redundant while also assisting in improving availability and performance. Additionally, you could see the DNS zone as a horizontal platform that connects all of a corporation’s subdomains.

As an illustration, if we have the domain name and a zone called inside of a DNS server, we may construct Resource Records for all of the TCP/IP devices inside the zone. This DNS server has been given permission to handle all DNS requests for domains, including,, etc.

Types of Domain Name System zone

  • Master (Primary) DNS zone. The binding capacity for the administrator to manage the domain name in this zone is to read and write instructions. This Primary (Master) zone is where you should make any necessary updates to your Domain Name System data (records). The Secondary (Slave) DNS servers and the rest of the network will get any changes or modifications.
  • Secondary DNS zone. It contains all of the Domain Name System information (records) you created in the Primary (Master) Domain Name System zone and is only a read-only replica of that zone. The terms “slave” and “backup” are frequently used to describe it. Keep in mind that records such as A, AAAA, MX, and so on cannot be created directly in the Secondary zone. Instead, it obtains all the information from the Primary through a process called zone transfer in the Domain Name System.
  • Reverse Domain Name System zone — Just like the Forward zone, the Reverse DNS zone is a management area of the domain name space that houses records. However, it accomplishes the opposite objective by connecting IP addresses to the corresponding domain names. It goes hand in hand with the use of Reverse DNS. Only PTR, SOA, and NS record types are available in this zone, which is likewise restricted.
  • Parked zone – Parked domains are ideal for this zone. It enables you to use a website that has a contact form, a title, and a description. It is frequently used for domain names up for auction or newly launched websites.

What is my DNS zone location?

Typically, you won’t need to check your DNS zone. Sometimes, you’ll need to alter or even record your DNS. For instance, you’ll need to know the server details if you purchase a new domain. In some cases, you might even move data to a new server.

You have resources at your disposal to check up on DNS data, including your DNS zone.

You can use whois/dig/nslookup and other tools like these that are built into your operating system or online applications that provide information about websites.

Speak with your website administrator if you’re still unsure of where to discover your zone. They can assist you in pulling your SOA and locating your zone. This can provide you with all the knowledge you require on your website. In addition, DNS zones can be modified and updated by zone administrators. This means that if you are the new administrator, your predecessor should have given you this information.


The DNS zone makes it much simpler and easier to handle the domain system namespace as a whole. Moreover, by disassembling it into smaller parts, the Domain Name System (DNS) offers decentralization and structure.

You should direct your domain name to various servers, such as web servers, mail servers, and other services if you want it to function correctly. To do this, you must first construct your domain name system zone and then add each of the necessary domain name system record kinds.

How does DNSSEC add an additional level of security?

DNSSEC is the most effective technique to secure your Domain Name System. We’ll explain why, what the phrase implies, and how you can benefit from it in this article. So, let’s keep it going.

The explanation of DNSSEC

DNSSEC is a collection of Security Extensions for the DNS that adds authentication and data integrity.

The Internet Engineering Task Force (IETF) invented it in the 1990s. Its primary goal is to provide an authentication method that uses digital signatures and public cryptography to prove the data’s origin. The data owner can use its private key to sign DNS data (DNS records) and ensure that the information is secure. Each recursive server can validate the data’s origin by comparing it to the public key.

It’s a complete chain of trust, beginning with the root server and ending with the exact hostname. Except for the root zone, which has nothing on top of it, each zone is signed by the one above it.

If the recursive server cannot authenticate the data for some reason, it will discard it and try again. It’s always better to be safe than sorry.

Is it advantageous?

The importance of DNSSEC may be summed up in two statements:

  1. You can ensure that the DNS data (DNS records) has not been tampered with by using DNSSEC. Consider what would happen if a cybercriminal modified DNS records on the route to the customer. The client can obtain a modified version of the product. A record that points to a server under the lousy actor’s control. There is a risk that the client’s data will be stolen. As a result, DNS cache poisoning is less likely. 
  2. Authentication of DNS data from a source. You can be sure that the data comes from a legitimate source and that the authoritative name server is valid using DNSSEC. It will prevent any bogus server forecasts.

Where can you get DNSSEC?

DNSSEC is not set up automatically. It is, however, straightforward to set up. As a result, most DNS hosting companies include it as a standard feature.

A substantial number of domains do not support DNSSEC. However, their entire worth is negligible. It can be used by well-known generic top-level domains (gTLDs) and country-code top-level domains (ccTLDs).

Simply enable it in the control panel of your DNS hosting provider to get started. Then look for DNSSEC and click “enable” for each DNS zone you want. After that, you’ll get a DS (Delegation Signer) record, which you should point to your domain’s registration information.


The decision to adopt DNSSEC to maintain DNS security is a wise one. Nowadays, cyber threats and direct DNS attacks are commonplace. Of course, DNSSEC is expensive, but you already know that the cost of preventing a criminal attack is always less than the cost of repairing the unintended consequences of a criminal attack.
