A DNS zone is a distinct portion of the domain name space that is managed by a specific entity. A DNS zone contains the DNS records for a domain and potentially its subdomains. A zone file is a text file that describes the zone and contains mappings between domain names and IP addresses. Zone management involves adding, modifying, and deleting DNS records to control how traffic is routed to your domain.
