What is a WHOIS lookup?

A WHOIS lookup queries the domain registration database to return information about who registered a domain, when it was created, when it expires, which registrar manages it, and which name servers it uses.

DNSSEC (DNS Security Extensions) adds cryptographic signatures to DNS records, protecting against spoofing and cache poisoning attacks. A signed domain provides stronger authenticity guarantees for visitors.

WHOIS Lookup — Domain Registrar & Expiry

About WHOIS & Domain Registration

What is WHOIS?

WHOIS is a query protocol used to look up registration records for domain names. It returns details including the registrar, registration and expiry dates, name servers, and contact information where not redacted for privacy.

GDPR & Privacy

Since 2018, most domain registrars redact personal contact information from public WHOIS records under GDPR. Technical data such as dates, name servers, and registrar details remain publicly available.

Expiry & Renewal

Domain registrations must be renewed periodically. Our tool shows exactly how many days remain before a domain expires — with colour-coded urgency for domains expiring within 90 days.

DNSSEC

DNS Security Extensions add cryptographic signatures to DNS records, protecting against spoofing and poisoning attacks. A signed domain provides stronger authenticity guarantees for visitors.

Frequently Asked Questions

Why is registrant information redacted?

Most registrars now hide personal contact information under GDPR and similar privacy regulations. This is completely normal and does not indicate anything suspicious about the domain owner.

What does clientTransferProhibited mean?

This status code means the domain is locked against transfers to another registrar. It is the default and recommended security setting preventing unauthorized domain hijacking.

How accurate is this data?

Our tool queries RDAP — the official IANA-standard replacement for WHOIS — directly. Data is as fresh as the registry allows, typically updated within minutes of changes. Results are cached for 12 hours for performance.

Can I look up a subdomain?

Subdomains are not independently registered. If you enter blog.example.com, the tool automatically looks up example.com and shows its registration details, with a notice explaining the reduction.

Can I look up any domain?

We support all major gTLDs, new gTLDs, and 840+ second-level registry TLD combinations across ccTLDs worldwide. A small number of country-code TLDs restrict public WHOIS access entirely.
