WHOIS Lookup

What is WHOIS data?

WHOIS data is a public record of information about an internet domain name. When a domain is registered through a registrar like GoDaddy, Namecheap, or Google Domains, the registrant provides information that is then stored in a WHOIS database. This data typically includes the domain owner's name and contact details (or a privacy-proxy), the registrar, nameservers, the creation date, the expiration date, the last update date, and the domain status. WHOIS records are maintained by ICANN-accredited registrars and are accessible through free query tools like ours.

How our WHOIS lookup works

Our tool runs in your browser and asks public RDAP servers for the current domain record. RDAP is the modern JSON replacement for many WHOIS queries, so it can return structured registration dates, registrar information, nameservers, domain status codes, and DNSSEC details when a registry publishes them. This is useful for:

• Due diligence - Checking how long a domain has existed before trusting a sender, vendor, or website.
• Market research - Reviewing registration patterns around brands, products, or campaigns.
• Fraud investigation - Checking registrar, status, and age signals for suspicious domains used in phishing campaigns.
• Domain investment - Reviewing expiry dates, locks, and nameserver changes before making acquisition decisions.
• Email deliverability audits - Cross-referencing sender domains against registration data to evaluate sender legitimacy.

What information is included in a WHOIS record?

A standard WHOIS record for a generic top-level domain (gTLD) like .com, .net, or .org includes the following fields:

• Domain name - The registered domain string.
• Registrar - The ICANN-accredited company that manages the registration.
• Registrant details - Name, organization, email, phone, and mailing address, often redacted behind privacy services post-GDPR.
• Administrative & technical contacts - Separate contacts for admin and DNS/tech issues.
• Creation date - When the domain was first registered.
• Updated date - When the record was last modified.
• Expiration date - When the registration ends unless renewed.
• Nameservers - The DNS servers responsible for resolving the domain.
• Status codes - EPP codes indicating locks, holds, or pending operations.

WHOIS privacy and GDPR

Since GDPR came into effect in 2018, most registrars redact personal data from public WHOIS output for European registrants, replacing names, emails, and phone numbers with proxy or privacy-service values. Business domains and non-EU registrants often still show full contact information. For this reason, WHOIS data should be treated as a directional signal rather than ground truth. Combine it with other sources (DNS, certificate transparency logs, archive snapshots) when doing serious investigations.

Frequently asked questions

Is WHOIS lookup free?

Yes. WHOIS and RDAP records are public, and this lookup tool is free to use without creating an account.

How often is WHOIS data updated?

Registrars push updates in real time when a registration changes, but WHOIS databases reflect those changes with varying latency, typically minutes to hours for gTLDs and up to a day for some ccTLDs.

Can I look up ownership history?

Public WHOIS only shows the current record. Historical WHOIS ("WHOIS history") is a paid service offered by specialized providers who snapshot records over time.

Why is some contact information hidden?

Privacy services and GDPR compliance redact personal data. This is legitimate behavior, not an error. Business-owned domains and some jurisdictions still display full records.

How is WHOIS different from DNS lookup?

WHOIS tells you who owns a domain and when. DNS lookup tells you where a domain points - the IP addresses and mail servers it resolves to. Both are useful for different purposes; our IP lookup tool covers the DNS side.
