WHOIS & Domain Lookup

Look up any domain's registration data — registrar, dates, status codes, nameservers, and DNSSEC — using live RDAP data from the registry.

WHOIS & Domain Lookup: Enter a domain name and click Lookup. The tool queries the domain's official registry via RDAP and returns its registrar, registration and expiry dates, registry domain ID, EPP status codes, nameservers, DNSSEC status, and any public contact information.

Key Takeaways

WHOIS shows who registered a domain, when, through which registrar, and when it expires
RDAP is the official successor to WHOIS — structured, accurate, and free to query
Personal contact details are usually redacted under ICANN/GDPR privacy rules
Domain status codes (e.g. clientTransferProhibited) reveal lock and transfer state
Expiry dates help you catch renewals before a domain drops or someone else grabs it

What is WHOIS & Domain Lookup?

WHOIS & Domain Lookup — A WHOIS lookup retrieves the public registration record of a domain name — including its registrar, creation and expiration dates, status codes, nameservers, and DNSSEC status — using RDAP (Registration Data Access Protocol), the modern, standardized replacement for the legacy WHOIS protocol.

This WHOIS & Domain Lookup tool pulls a domain's registration record directly from its authoritative registry using RDAP — the IETF/ICANN standard that replaces legacy WHOIS. Enter any domain to see the registrar and IANA ID, creation/updated/expiry dates, registry domain ID, EPP status codes, nameservers, DNSSEC status, and the public portion of registrant, administrative, and technical contacts. Used by developers, domain investors, security analysts, and brand-protection teams to verify ownership, monitor expiry, and audit domain configuration.

How to Use WHOIS & Domain Lookup

1
Type a domain name (e.g. example.com) into the input field. Protocol, www, and paths are stripped automatically.
2
Click 'Lookup' to query the domain's registry over RDAP.
3
Review the categorized results: Domain Information, Dates, Registrar, Nameservers, DNSSEC, and Contacts.
4
Check the expiry date and status codes — a red expiry warning appears when fewer than 30 days remain.

Key Features

Registrar name and IANA Registrar ID

Creation, last-updated, and expiration dates with days-to-expiry

About WHOIS & Domain Lookup

WHOIS vs. RDAP

WHOIS is the decades-old protocol for querying domain registration data, but its free-text output is inconsistent across registries and is being phased out. RDAP (Registration Data Access Protocol) is its official replacement — it returns structured JSON, supports secure access and internationalization, and is mandated by ICANN. This tool queries RDAP directly using the authoritative IANA bootstrap registry, so the data you see comes straight from the registry responsible for each TLD.

Why contact data is redacted

Since GDPR and ICANN's Temporary Specification, most registries redact personal contact details (registrant name, email, address) from public records to protect privacy. You'll still see the registrar, dates, status codes, nameservers, and DNSSEC — and a registrar abuse contact for reporting. Non-public data can only be requested through ICANN's RDRS for legitimate, lawful purposes.

Understanding status codes

EPP status codes describe a domain's state. clientTransferProhibited means the registrar has locked the domain against transfers (a good anti-hijacking measure). addPeriod marks a freshly registered domain. pendingDelete and redemptionPeriod indicate a domain on its way to expiry and potential re-registration.

Frequently Asked Questions

What is a WHOIS lookup?: A WHOIS lookup retrieves a domain's public registration record — its registrar, creation and expiry dates, status codes, nameservers, and DNSSEC status. This tool uses RDAP, the modern standardized replacement for the legacy WHOIS protocol.
What is the difference between WHOIS and RDAP?: WHOIS returns inconsistent free-text data and is being deprecated. RDAP returns structured JSON, supports authentication and internationalized domains, and is the official ICANN-mandated successor. This tool queries RDAP for accurate, machine-readable results.
Why can't I see the owner's name and email?: Under GDPR and ICANN privacy rules, registries redact personal contact details from public records. You'll still see the registrar, dates, status, nameservers, and DNSSEC, plus a registrar abuse contact. Non-public data requires a formal request through ICANN's RDRS.
How do I check when a domain expires?: Enter the domain and look at the 'Expires' field under Dates. The tool also shows days remaining and highlights the date in red when fewer than 30 days are left.
Can I check if a domain is available to register?: Yes. If no registration record exists in the registry, the tool reports the domain as available (unregistered). Confirm final availability and pricing at a registrar, as some names are premium or reserved.
Does this work for all domain extensions (TLDs)?: It works for virtually every TLD that publishes RDAP — which now covers all gTLDs (.com, .net, .org, .tech, .dev, .io, and more) and many ccTLDs, resolved automatically via the IANA RDAP bootstrap.
What does clientTransferProhibited mean?: It's an EPP status code indicating the registrar has locked the domain to prevent unauthorized transfers. It's a recommended security setting for domains you own.
