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 picusha.net and a zone called picusha.net 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 picusha.net domains, including www.picusha.net, info.picusha.net, 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.

Conclusion

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.
