Zone File
A text file containing all DNS records for a domain: the complete DNS configuration.
A zone file is a plain text file that contains all the DNS records for a domain, stored on the authoritative nameserver. It defines everything about the domain's DNS: its A records, MX records, CNAME records, TXT records, nameservers, and more. Each line in the zone file is a DNS record. When you edit DNS records through a web interface (like Cloudflare's dashboard or your registrar's control panel), you are modifying the zone file behind the scenes. System administrators can also import and export zone files directly for bulk DNS management.
