Enter a domain and get its real registration date, registrar, and DNS footprint — pulled live from RDAP (the registry-run successor to WHOIS) and DNS, not guessed or cached.
Updated August 2026
Why this tool exists
Running a solo agency means I'm the one deciding whether an inbound message is worth a reply, a vendor is worth a deposit, or a "partnership" pitch is worth 20 minutes on a call. The fastest sanity check I have isn't a background check service — it's the domain itself. RDAP (Registration Data Access Protocol, RFC 9083) gives every registry-run fact about a domain in one structured query: when it was registered, who the registrar is, and its current status.
A domain registered three days ago pitching a six-figure partnership is a different conversation than one that's been live for eight years. Neither is proof of anything on its own — but paired with a DNS footprint check (does it actually receive mail, is it sitting on a recognized DNS provider), it's a fast, free first filter before you spend real time.
Pair it with the Email Deliverability Checker if you're the one sending — and vet your own outreach copy with the Cold Outreach Compliance Checker before it goes out.

Reference
| Age | What it typically means | Signal |
|---|---|---|
| Under 30 days | Freshly registered — common for both new legitimate ventures and disposable phishing/scam domains | Extra scrutiny |
| 30 days – 6 months | New but not same-day — could be a real launch, still worth a second look | Moderate |
| Over 6 months | Old enough to rule out a same-day throwaway domain | Lower risk (not zero) |
This is a heuristic, not a rule — treat it as one input among several, never a standalone verdict.
Quick answers
RDAP (Registration Data Access Protocol, RFC 9083) is the modern, structured-JSON successor to WHOIS. Registries have been migrating to it since ICANN mandated it, and it returns machine-readable fields (registration date, registrar, status codes) instead of a loosely-formatted text blob. This tool queries RDAP directly, not a scraped WHOIS mirror.
A few reasons: the domain isn't registered, the TLD's registry doesn't publish RDAP data yet (rare in 2026 but still true for a handful of ccTLDs), or the registry's RDAP endpoint doesn't send CORS headers — which blocks a browser-based tool like this one from reading the response even though the data exists. If a lookup fails, the tool tells you which of these it is rather than guessing.
No. Plenty of legitimate businesses launch new domains — rebrands, new product lines, agencies spinning up a project subdomain. Domain age is one signal among several, not a verdict on its own. Combine it with the DNS footprint (does it receive mail, is it on a real DNS provider) and, for outreach specifically, the Email Deliverability Checker.
No — this is a fast, free, DNS-level sanity check, not a substitute for verifying a business registration, checking references, or reading a contract. Use it as a first-pass filter before you invest more time.
No. The domain is sent from your browser directly to rdap.org and dns.google — both public, keyless lookup services. Nothing is logged by SkynetJoe.
