WHOIS Lookup

Registrar, dates, and nameservers for any domain — via RDAP, WHOIS's modern successor.

What this checks

This lookup queries RDAP — the Registration Data Access Protocol — which is the structured, JSON-based replacement for the old port-43 WHOIS service. Where classic WHOIS returned free-form text that every registry formatted differently, RDAP returns typed fields that always mean the same thing, so the registrar, the registration and expiry dates, the nameservers, and the domain status codes all come back cleanly labelled rather than scraped out of prose.

The data comes straight from the authoritative registry for the domain's TLD, not from a cache or a third-party database. That makes it current, but it also means coverage varies: a handful of country-code TLDs still don't publish an RDAP endpoint, and for those the lookup can only tell you that registration data isn't available rather than inventing it.

How to read the results

The details grid names the registrar the domain is currently held through, the date it was first registered, when the current registration expires, and when the record was last changed. Below that, the nameservers list shows where the domain's DNS is authoritatively served — a quick way to see which DNS host or CDN is actually in charge. The status codes are EPP status values set by the registrar or registry; they describe locks and pending operations on the domain rather than anything about its content.

If a domain isn't registered at all, you'll get a plain "Not registered" answer and a link to check availability instead. If the TLD doesn't support RDAP, you'll see a short note saying so — that's not an error, just a registry that hasn't published a modern endpoint.

Why the owner's details are redacted

You'll notice there's no registrant name, email, or street address here, and that's deliberate. After GDPR took effect, ICANN told registrars to stop publishing personal contact details in public registration data, so for the vast majority of domains those fields are now redacted at the source. Registrars also sell privacy or proxy services that substitute the provider's own details for the owner's, which hides even the organisation behind an intermediary.

FAQ

Why can't I see the owner's name?

Public registration data no longer includes registrant contact details for most domains. Following GDPR, ICANN directed registrars to redact personal information, and many owners add a privacy or proxy service on top, which replaces even the organisation name with the provider's. To reach the actual owner you generally have to use the registrar's contact form or a legal process, not a lookup.

What is RDAP?

RDAP is the Registration Data Access Protocol, the successor to the text-based WHOIS service that ran on port 43. It returns the same registration facts as structured JSON with consistent field names, supports internationalised data properly, and lets registries apply access controls — which is why modern lookups, including this one, query RDAP rather than raw WHOIS.

Why does the expiry differ from my registrar's?

The expiry shown here is the registry's authoritative record. Your registrar's dashboard sometimes displays a different date because it accounts for an auto-renew, a grace period, or a recent renewal that hasn't yet propagated to the registry. If the two disagree, treat the registrar's billing date as what governs your renewal and the registry date as the underlying truth.

What do the status codes mean?

Status codes are EPP values describing the domain's state at the registry. Codes like clientTransferProhibited are protective locks that stop a domain being moved or deleted without your action, while pending states signal an operation in progress. Seeing several "prohibited" statuses is normal and healthy — it usually means the domain is locked against unauthorised transfers.
