Updated on 16-Mar-2026 1K+ Views

The Domain Name System (DNS) Zones are partitions of the DNS namespace that enable distributed administration of domain names. A DNS zone represents a portion of the DNS tree structure that is managed by a specific administrator or organization, allowing for decentralized control over different parts of the global DNS infrastructure. DNS zones solve the scalability problem that would arise if the entire DNS system were managed by a single authority. By dividing the DNS namespace into manageable zones, administrative responsibilities are distributed, and the workload on individual nameservers is reduced. Multiple zones can exist on the same physical ...

In response, the server provides registration information for the requested domain or IP address. The Internet Corporation for Assigned Names and Numbers (ICANN) governs the WHOIS ...
