Domain lookup
Who owns a domain, where its nameservers point, when it was registered, when it expires. Uses RDAP (the modern HTTP-based WHOIS replacement).
Privacy note: WHOIS data is public per ICANN rules but most registrants now use privacy services that mask their personal name and contact details. Expect to see "REDACTED FOR PRIVACY" or a proxy service in those fields — that's normal post-GDPR.
In one line: MyIPSpeed WHOIS Lookup queries the RDAP protocol — the modern replacement for legacy WHOIS — to return registrant, registrar, name servers, creation/expiration dates, and EPP status codes for any domain.
About WHOIS and RDAP
WHOIS is the legacy protocol for looking up registration data — who registered a domain, with which registrar, when, and through which name servers. RDAP (Registration Data Access Protocol) is the modern HTTPS-based replacement, standardized at the IETF in 2015, and is what this tool queries directly.
What you get back
Registrant name (or privacy proxy), registrant organization, registrar name + IANA ID, creation date, expiration date, last-updated date, registration status codes (EPP codes like clientTransferProhibited), and the authoritative name servers for the domain. Some TLDs return more, some less.
Why so much is redacted
Since GDPR (2018) and ICANN policy changes, personal data on most domain registrations is hidden by default. Names and emails for individuals are replaced with privacy services or registrar-provided proxies. Organizational registrations still show real data. Some country-code TLDs (e.g., .de, .ch, .nl) restrict WHOIS access entirely.
WHOIS vs. RDAP
WHOIS is free-form text over port 43; RDAP is structured JSON over HTTPS. Both return the same data when the registry supports both. We query RDAP — it is faster, structured, supports authentication, and is the long-term replacement. WHOIS is being phased out by IANA over the next several years.
