WHOIS Information
What is WHOIS Lookup?
WHOIS Lookup is a query and response protocol used to search databases that store registered users or assignees of internet resources, particularly domain names. When you perform a WHOIS lookup, you retrieve detailed information about domain ownership, registration dates, expiration dates, registrar information, and nameserver details. This tool is essential for domain research, cybersecurity investigations, trademark protection, and verifying domain availability.
Why Use WHOIS Lookup?
WHOIS lookup serves multiple critical purposes in the digital world. Website owners use it to verify domain registration details and ensure their information is accurate. Security professionals rely on WHOIS data to investigate phishing attempts, identify malicious domains, and track down cybercriminals. Legal teams use WHOIS information for trademark disputes and intellectual property protection. Businesses use it to research competitors, verify potential partners, and identify available domain names for acquisition. The transparency provided by WHOIS data helps maintain accountability and trust in the domain name system.

Privacy and WHOIS
Many domain registrars now offer WHOIS privacy protection services that mask personal information from public WHOIS databases. This protects domain owners from spam, identity theft, and unwanted solicitation while still maintaining the essential technical information needed for domain operation. GDPR regulations have also impacted WHOIS data availability, with many European registrars redacting personal information to comply with privacy laws.

WHOIS data is updated in real-time when changes are made to domain registration, but it may take 24-48 hours to propagate globally.
Can I use WHOIS to find expired domains?

What does domain status mean?
