About Us
FetchWhois is a free WHOIS and ICANN RDAP domain lookup tool built for developers, security researchers, and anyone who needs fast, accurate domain registration data.
Our Mission
Domain registration data should be openly accessible without paywalls or data harvesting. FetchWhois queries the official IANA RDAP bootstrap registry directly, returning structured, authoritative data straight from the source — no third-party middlemen, no tracking pixels, no noise.
Fast & Live
Every lookup hits authoritative RDAP servers in real time — results are always fresh, not stale cache.
Privacy First
We don't store your queries or sell your data. Your lookups stay between you and the RDAP servers.
IANA Standard
Powered by the official IANA RDAP protocol — the modern, structured replacement for legacy WHOIS.
Who We Are
FetchWhois is an independent project maintained by a small team of developers passionate about open internet infrastructure. We believe that transparent access to domain registration data benefits the entire internet ecosystem — from security researchers tracking phishing domains to businesses performing due diligence on new vendors.
Built on Open Standards
RDAP (Registration Data Access Protocol) is the ICANN-mandated successor to WHOIS, offering structured JSON responses, internationalization support, and fine-grained access control. FetchWhois uses the IANA RDAP bootstrap file to route each lookup directly to the authoritative registry for any TLD — ensuring the most accurate, up-to-date registration data possible.
