Free WHOIS & Domain Age Lookup
Look up a domain’s registration details via RDAP (the modern WHOIS) — registrar, creation date and age, expiry date, nameservers and registrar transfer/delete locks. Newly-registered and soon-to-expire domains are flagged.
By scanning, you confirm you own or have permission to test this domain. Not a substitute for manual penetration testing.
What this whois lookup checks
How it works
Read-only· RDAP registry lookup — no traffic to your servers- 1We query RDAP (the structured, modern WHOIS) for the domain’s registration record.
- 2We surface the registrar, creation date and age, expiry, nameservers and transfer/delete locks, and flag domains under 90 days old or expiring within 30 days.
- 3This reads the public registry only — your servers are never contacted.
What it doesn’t do: Some ccTLDs do not publish RDAP and registrars may redact contacts under privacy rules, so a few fields can be blank.
Why it matters
Domain age is a strong trust and risk signal — a huge share of phishing and fraud runs on domains registered days earlier. Expiry and registrar-lock status protect you from accidental loss and domain hijacking.
Frequently asked questions
Is the WHOIS lookup free?
Yes, and no sign-up is required. It uses RDAP — the standardized, structured successor to classic WHOIS.
Why does it sometimes show no data?
Some country-code TLDs do not publish RDAP/WHOIS data, and registrars may redact contact details under privacy rules. We still surface registration dates, nameservers and locks where available.
Why does domain age matter for security?
Attackers register fresh domains for phishing and malware because they have no negative reputation yet. A domain only days old warrants extra caution.
