Live RDAP lookup — nothing storedFrequently asked questions
What is RDAP and how is it different from WHOIS?
RDAP (Registration Data Access Protocol) is the modern, HTTPS-based, structured-JSON successor to legacy WHOIS, which uses a raw text protocol on port 43. This tool uses RDAP under the hood, since it's the ICANN-mandated replacement and works reliably over standard HTTPS.
Why does domain age matter?
A domain registered hours or days ago is a common signal used in phishing and scam detection. Established domains that have existed for years are generally, though not always, more trustworthy than brand-new ones.
Does this tool store the domains I look up?
No. Each lookup is a live, stateless call to the RDAP registry data -- nothing is logged or stored beyond standard, anonymized request metrics.
Can I use this in my own code?
Yes. This page calls the same free, public API endpoint you can call directly: GET /api/whois-lookup?domain=example.com. No signup or API key required.
