What Is A Dns Zone Dns is comprised logically of domains but physically of zones. a domain is a logical division of the dns name space whereas a zone is physical, as the information is stored in a file called a zone file. A dns zone is a distinct portion of the domain name space in the dns. this post explores the types of dns zones, how to find your dns zone records and more.
Dns Zones Explained Images Dns zones follows a hierarchical concept. therefore, namespace is subdivided into areas (zones) for this purpose. the purpose of dns zones is to permit easier control over multiple levels of website. as the number of resource records increases for single domain, it becomes complex to manage all of them. What is a dns zone file? a zone file is a plain text file stored in a dns server that contains an actual representation of the zone and contains all the records for every domain within the zone. Understanding the roles of dns zones and zone files reveals how the system is organized, maintained, and secured to support the seamless operation of the internet. a dns zone is a distinct administrative segment of the broader dns namespace. Dns zones split up the authority over different segments of the dns namespace—for instance, a domain and a subdomain—which gives administrators more precise control over dns records, dns name servers and other components. this partitioning can help streamline dns management and orchestration and distribute workloads across name servers.

Dns zone content can be stored in a file or in active directory domain services (ad ds). when the dns server stores the zone in a file: that file is in a local folder on the server. only one copy of the zone is writable. other copies, which are read only, are referred to as secondary zones. To better understand what a dns zone is and how it works, we first need to define the dns namespace. the dns namespace is like a filing system for websites. it organizes domains in a structured way. at the top of this hierarchy is the root zone, which serves as the starting point. Today, we're going deeper into a critical component of dns: zone files. these files are the actual blueprints that make the domain name system work behind the scenes. what is a dns zone file? a zone file is simply a text file that lives on authoritative dns servers. Zone files are simple text files with dns records. a zone file will contain the whole information for a domain: soa record, which indicates the start of authority. a records for ipv4 addresses. aaaa records for ipv6 addresses. cname records for canonical records that indicate the canonical domain.
