DNS History Lookup

Historical DNS Lookup retrieves past DNS records for a domain - showing how its A, MX, NS, TXT, and other records have changed over time. WhoisFreaks stores over 18.2B+ DNS records, enabling deep historical analysis.

DNS history is a cornerstone of threat intelligence. Analysts use it to: trace infrastructure pivots (when a threat actor moved a malicious domain to a new IP), correlate domains hosted on the same IP at the time of an attack, identify C2 server migrations, and build attack timelines. It's frequently queried in vulnerability disclosure and incident response workflows.

'DNS history' refers to the archived state of a domain's DNS records over time - what its A records, nameservers, MX records, and TXT records looked like at any given point in the past. Unlike a current DNS lookup (which queries live resolvers for today's records), DNS history shows the historical timeline of every change. Security teams use it for incident timelines, threat actors' infrastructure pivots are visible through it, and acquisition due diligence relies on it to verify how a domain has been used historically.

WhoisFreaks continuously collects DNS data, and the historical depth varies by domain popularity and TLD. High-traffic domains tend to have longer coverage. The database contains 18.2B+ DNS records across 6.5B+ hostnames.

Yes. Historical DNS Lookup covers all major record types including MX (mail servers) and NS (nameservers), so you can track changes in email routing or DNS hosting provider history. For a domain's current MX records, use the MX Lookup tool.

The current DNS Lookup tool queries live resolvers for today's records. Historical DNS Lookup retrieves archived snapshots from WhoisFreaks' database - showing what the records looked like at various points in the past, even if those records have since changed or been deleted.

Yes. The DNS History API returns paginated records with timestamps, suitable for integration into threat intelligence platforms, OSINT workflows, and security automation pipelines.
