Unlike security platforms that dump data and walk away, DNSReplay is designed to be explored.
Scrub through DNS record history like a video timeline. See how infrastructure evolved, step by step, without running a single API query.
Not sure when something changed? Search backward — find when a specific IP first appeared, or when a nameserver first showed up in your domain's history.
A, AAAA, MX, NS, TXT, CNAME, SOA, PTR — every record type, going back years. Complete infrastructure archaeology, not partial snapshots.
Export any historical snapshot as JSON, CSV, or a shareable link. Build DNS history into your workflows, reports, and investigations.
Reconstruct the timeline of a compromised domain. When did it first point to this IP? What nameservers were active during the breach window? Build your timeline from DNS history — not guesswork.
Monitor lookalike domains across DNS history. Catch domains that are freshly registered or have recently changed DNS — often the signal that a copycat site is about to go live.
Before you bid on an expired domain, see its full DNS history. What services were running on it before it dropped? Any red flags in the record timeline? Know what you're buying.
Build adversary profiles by correlating DNS history across targets. See when different domains shared the same nameservers — a strong signal of common control.
The internet remembers everything you do on it — except DNS.
The Wayback Machine proved there's immense value in browsing the web's past. Pages change, disappear, get rewritten — and archive.org was there.
DNS records change too. Infrastructure pivots. IPs get reassigned. Nameservers switch. And when you need that history — for a legal case, a security investigation, or just to understand what happened — it's usually gone. Or locked behind a $2,000/year security subscription.
DNSReplay exists because DNS history should be browsable, not just queryable. Because the internet's infrastructure history belongs to everyone.
