DNS zone – What is it?

DNS zone – What does it imply?

The Domain Name System (DNS) zone is a small but crucial component of the DNS system. Using this operating segment, DNS administrators can manage and govern their networks. In addition, many DNS zones probably make use of the same DNS server as you. Consequently, handling the entire namespace is simpler.

Furthermore, the entire Domain Name System (DNS) exists because of these divisions.

One Domain Name System zone, for instance, might apply to domain.net, blog.domain.net, and so forth. However, examining a particular subdomain as an independent website calls for dedicated management. Therefore, that subdomain will have to have its own zone.

Best practices for managing a Master DNS Zone

DNS zone categorizations

  • Primary DNS zone (Master) – This is the primary source of domain name information. In this zone, the administrator must be able to read or write instructions and manage the domain name. As a result, whenever you need to make changes or adjustments to your Domain Name System data (the records), you should do so in this Primary (Master) zone. All updates or changes will be propagated to the Secondary (Slave) DNS servers and the rest of the network from there.
  • A simple read-only copy of the Primary (Master) DNS zone, the Secondary (Slave) DNS zone contains all of the domain name system data (records) you added there. You may have noticed that it is frequently referred to as a slave or backup zone. It is crucial to keep in mind that records like A or AAAA recordings, MX records, etc., cannot be created directly in the Secondary Zone. Instead, it uses a DNS zone transfer method to get all the information from the Primary.
  • Reverse DNS zone – The Reverse zone, like the Forward (Primary), is a portion of the domain name space used for administration and record storage. It accomplishes the exact reverse, connecting the IP addresses to their matching domain names. It is related to the use of Reverse DNS. This zone is also restricted and only includes the record types PTR, SOA, and NS.

DNS Zone file – What exactly is it?

The Domain Name System administrator for each of the delegated divisions, known as DNS zones, can add instructions, settings, authentication methods, and other information to the zone’s DNS zone file. They appear as DNS records, which are straightforward text instructions that other computers and sporadically people may read and understand.

What levels of DNS zones are there?

The Domain Name System (DNS) defines top-level domains (such as “.com”), second-level domains (such as “example.com”), and lower-level domains, sometimes known as subdomains (such as “info.example.com”) (DNS). At each of these levels, a zone may exist.

At each level of the DNS system’s hierarchy (DNS Hierarchy), there is a Name Server hosting a zone file that contains the zone’s trusted, accurate DNS records.


Let’s recap. You can store name information for one or more of the domains you control in a DNS zone. To improve management, organization, or speed, you can segment your network into a number of subordinate DNS zones. Although it is more likely to be a subspace, the DNS zone you use for HA pools can be your organization’s global DNS zone.
