What is a DNS Zone?

A DNS zone refers to a certain portion or administrative space within the global Domain Name System (DNS). All entries within a domain's zone, such as subdomains (sub.domain.com), or an MX record (which specifies the server location of emails) are within this zone. Where is this located? It depends on what Name Servers (NS) you are using. We offer certain alternatives ourselves: our own hosting space or our managed DNS at the registry level. The zones are accessible through the hosting platform's management interface, or through the domain, management interface accordingly. 

A DNS Zone has several fields to know:

  • (Sub)domain: domain or subdomain entry
  • TTL: "time to live" refers to the number of seconds before the refresh
  • Data Class: IN stands for Internet
  • Type of record: A, MX, TXT, CNAME
  • Value: webname, IP, or other value that should be entered

Types of Records

Here is a list of the common DNS Zone entries we often refer to:

  • A: entry refers to an IP address
  • CNAME: entry refers to a webname
  • MX: Webname of the email server
  • TXT: Machine-readable data commonly used for SPF and DKIM records
  • NS: Webname of the Name server in which the domain is located.
