A DNS zone is a distinct, contiguous portion of the domain name space in the Domain Name System (DNS) for which administrative responsibility has been delegated to a single manager. A zone typically represents a domain, subdomain, or a collection thereof. It contains DNS records, such as A, AAAA, MX, and TXT records, that map domain names to IP addresses or other resources. DNS zones are commonly used to manage the DNS records for a website, email server, or other internet service, allowing administrators to control how these services are accessed and configured.
