Look up WHOIS records for one or many domains to get registrar details, contact information, and key registration dates for due diligence or outreach.
This tool retrieves the public WHOIS record for any domain name. WHOIS is the official, publicly accessible database of domain registrations, managed by the Internet Corporation for Assigned Names and Numbers (ICANN). When a domain is registered, the owner's details are recorded, and this tool lets you query that record. You can look up a single domain or provide a list of domains to check in bulk. The output includes the name of the registrar that manages the domain, the dates it was registered and when it expires, and the last time the record was updated. It also provides the nameservers the domain points to and any official contact details—such as for the registrant, administrator, or technical manager—that aren't hidden by a privacy service. ### Who is this for? * **Marketing & Sales Teams:** Find the owners of websites for partnership proposals, sales outreach, or link-building campaigns. * **Cybersecurity Analysts:** Investigate suspicious domains, identify their registrars, and gather information for abuse reports or takedown requests. * **Domain Investors:** Research domain ownership history, track expiration dates of valuable domains, and perform due diligence before an acquisition. * **Legal & Brand Protection Teams:** Identify the owners of domains infringing on trademarks and gather evidence for cease-and-desist letters or UDRP complaints.
Decide if you want to check one domain or a list of them.
For a single check, enter the domain name (e.g., example.com) into the 'Single Domain' field.
For a bulk check, enter each domain on a new line in the 'Multiple Domains' field.
