Interactive intelligence tool

Run the check, then ship the workflow

Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.

Start with the live form

Enter a domain, URL, IP, email, or record and get a focused result without setup.

Review decision-ready signals

Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.

Automate the workflow that works

Use the request and response examples to turn a one-off check into an API call or recipe.

Frequently asked questions

What is WHOIS history?

DomScan WHOIS History is an observation log, not a global archive. A fresh, successful RDAP-backed GET /v1/whois or GET /v2/whois lookup can add at most one normalized snapshot per domain per UTC day. Cached responses, bulk requests, history reads, and traditional WHOIS-only fallbacks do not add snapshots.

What changes are tracked?

DomScan automatically compares the observed registrar name, expiry value, nameservers, status codes, DNSSEC, transfer-lock state, and privacy/redaction detection. It stores creation and update dates but does not compare them automatically, and it does not store historical registrant identity or contact fields. Snapshots do not prove domain ownership or a transfer.
