WHOIS Lookup

Look up the registration record for any domain. Enter a name and this tool queries the live WHOIS and RDAP systems and shows the registrar, the creation, update and expiry dates, the name servers, the EPP status codes and the full raw WHOIS record. It is the fast way to see who manages a domain, when it was registered, and when it needs renewing.

How to use the WHOIS Lookup

Enter a domain (for example example.com) and press Look up WHOIS. The tool runs two lookups in parallel and merges them:

• RDAP — the modern, structured replacement for WHOIS, which returns clean machine-readable data for the registrar, dates and status.
• WHOIS (port 43) — the classic text record, which fills in fields RDAP sometimes omits and gives you the full raw record to read.

You get the registrar and its IANA ID, the creation date (and the domain's age), the expiry date (and days remaining), the last-updated date, the name servers, the EPP status codes, the DNSSEC state, and any registrant details the registrar still publishes. Use Copy raw WHOIS to grab the full text for a ticket or record.

What a WHOIS record is

Every domain registration is recorded in a public database that maps the name to its registrar (the company you bought it through), key dates, and the name servers that run its DNS. WHOIS is the decades-old protocol for querying that database: you connect to a registry's WHOIS server on port 43, send the domain name, and get back a block of text.

The record typically contains:

• Registrar and its IANA-assigned ID — who currently manages the domain.
• Creation, updated and expiry dates — when it was first registered, last changed, and when the registration lapses.
• Name servers — the authoritative DNS servers, which tell you where the domain is actually hosted or proxied (for example Cloudflare).
• EPP status codes — machine states like clientTransferProhibited (a transfer lock) or pendingDelete.
• DNSSEC — whether the domain's DNS is cryptographically signed.

Since 2018, GDPR has caused most registrars to redact personal registrant contact details (name, email, phone) for individuals, so those fields are often hidden. The administrative data — registrar, dates, name servers, status — remains public. Modern registries also publish RDAP, a JSON-based successor that returns the same facts in a structured, reliable form; this tool reads both and shows you the merged result plus the original raw record.

Common use cases

• Checking a domain's renewal date — see exactly when a domain expires so you can renew before it drops.
• Researching a domain before buying — confirm the registrar, age and status of a name you want to acquire.
• Verifying ownership signals — see the registrar and name servers to sanity-check that a domain is configured the way you expect.
• Investigating a suspicious domain — a brand-new creation date and a privacy-protected registrant are common phishing signals.
• Auditing a portfolio — pull the registrar, dates and status for each domain you manage and copy the raw record into your asset register.

WHOIS vs RDAP: why this tool uses both

• WHOIS is plain text with no standard format, so every registry lays its fields out differently. It is universally available and still the only way to read some country-code TLDs, and it gives you the full human-readable record.
• RDAP (Registration Data Access Protocol) returns structured JSON with consistent field names, standard status codes, and proper internationalisation. It is mandatory for all gTLDs (.com, .net, .org and the new TLDs) but many ccTLDs do not offer it yet.
• This tool merges them: it prefers RDAP's clean values where available and falls back to WHOIS, while always showing the raw WHOIS text. That gives you the most complete, accurate picture in one lookup.
