DNSdata
DNSdata is a term used in information technology to refer to the structured data derived from the Domain Name System (DNS) that is collected, stored, and analyzed for operational, security, and performance purposes. In practice, DNSdata can encompass a range of data elements, including DNS query logs from resolvers and authoritative servers, response records such as query type, RCODE, and DNSSEC validation status, timing information like resolution latency, and metadata about clients or networks that initiated the queries. It may also include zone data and data from DNS security telemetry.
Data can be collected at different points in the DNS workflow: recursive resolvers, authoritative servers, or
Common uses include network performance analysis, capacity planning, troubleshooting, detection of anomalies and abuse such as
Because DNS data can reveal user behavior and network topology, many organizations implement data minimization, anonymization,
Challenges include the scale of data, encryption of DNS traffic (which reduces visibility), and the need for
