Powered by the official IANA RDAP protocol

ICANN Lookup

Perform a free ICANN lookup for any domain name. FetchWhois uses the ICANN-standardized RDAP protocol to return authoritative registration data — the registrar, key dates, nameservers, DNSSEC and contact details — straight from the registry.

Try:

Instant results

Real-time WHOIS domain lookups resolved directly from authoritative RDAP servers — no queues, no waiting.

ICANN-grade accuracy

Every ICANN lookup pulls structured data straight from the registry and registrar, following the official RDAP standard.

Hundreds of TLDs

From .com and .org to .io, .dev and country-code domains — powered by the IANA bootstrap registry.

Private & simple

No sign-up and no domain upsells. Just clean, trustworthy WHOIS results every time.

How to perform an ICANN lookup

The ICANN-standardized RDAP protocol, made simple.

1Step 1

Enter a domain name

Type any domain name into the search box. FetchWhois supports all gTLDs and many ccTLDs that have implemented the ICANN-required RDAP service.

2Step 2

FetchWhois queries via the ICANN RDAP standard

We resolve the authoritative RDAP endpoint from the IANA bootstrap registry — the same registry that ICANN maintains to direct RDAP queries for every supported TLD.

3Step 3

View complete ICANN registration data

The full registration record — registrar, dates, status codes, nameservers, DNSSEC and entity contacts — is returned from the authoritative RDAP server and displayed in a clean layout.

What is an ICANN lookup and how does it differ from a standard WHOIS?

When people refer to an ICANN lookup, they are referring to a query against the ICANN-standardized Registration Data Access Protocol (RDAP). ICANN (the Internet Corporation for Assigned Names and Numbers) mandates that all accredited registrars and gTLD registry operators maintain RDAP services and make registration data available through them. An ICANN lookup therefore means a lookup that goes through official, ICANN-sanctioned channels — as opposed to querying an unofficial WHOIS aggregator or a cached database.

ICANN governs the global domain name system through contracts with registries (who operate TLDs) and registrars (who sell domains to registrants). The IANA (Internet Assigned Numbers Authority), a function of ICANN, maintains the bootstrap registry that maps each TLD to its authoritative RDAP server. FetchWhois uses this IANA bootstrap file for every lookup, ensuring that every ICANN lookup goes to the right authoritative source.

The move from legacy WHOIS to RDAP was one of ICANN's major technical initiatives. RDAP provides structured, consistent, HTTPS-secured registration data while also accommodating the privacy requirements of GDPR and other regulations through differentiated access. An ICANN lookup today returns the same core registration data as legacy WHOIS, but in a more reliable, secure and standardized format.
