WHOIS Lookup: Find Domain Registration & Ownership Details Instantly
The WHOIS Lookup Tool by HasheTools helps you uncover complete registration and ownership details of any domain name. Instantly check who owns a domain, when it was registered, its expiry date, registrar, and DNS configuration, all in one place.
Whether you’re investigating a website, verifying ownership, or researching a potential domain purchase, our WHOIS Lookup gives you accurate and real-time results directly from global WHOIS and RDAP servers.
What Is WHOIS Lookup?
A WHOIS Lookup is a query that retrieves publicly available data about a registered domain name.
This information comes from global databases maintained by ICANN (Internet Corporation for Assigned Names and Numbers) and domain registrars.
With WHOIS, you can identify:
- Domain owner or registrant (when publicly available)
- Registrar details: which company manages the domain
- Registration and expiration dates
- Nameservers: where the domain’s DNS is hosted
- Domain status codes: like active, on hold, or expired
Why Use HasheTools WHOIS Lookup?
Our WHOIS Lookup tool is designed for speed, accuracy, and convenience. It’s an essential utility for:
- Verifying domain ownership before buying or transferring a domain
- Checking domain expiration to renew or backorder a name
- Investigating suspicious websites or potential phishing attempts
- Troubleshooting DNS or hosting issues
- Analyzing competitors’ domain setups
HasheTools uses both WHOIS and RDAP protocols to ensure you get the most current and reliable data.
How WHOIS Lookup Works
When you enter a domain name (like example.com), our system:
- Connects to the domain’s registrar or registry WHOIS database.
- Retrieves details such as registration, contact, and DNS records.
- Displays the data instantly in a clean, easy-to-read format.
If WHOIS data isn’t available, the lookup automatically switches to the RDAP protocol, the modern replacement for WHOIS, to fetch up-to-date results with better security and structure.
What is RDAP (Registration Data Access Protocol)?
RDAP is the next-generation version of WHOIS. It was developed by the IETF (Internet Engineering Task Force) to improve data accuracy, access control, and international support.
Key Benefits of RDAP:
- Provides secure and standardized access to registration data
- Supports JSON format for structured, machine-readable output
- Allows differentiated access; only authorized users can see sensitive data
- Offers real-time synchronization with registry databases
HasheTools WHOIS Lookup uses RDAP as a fallback, ensuring you always get the most recent and accurate data possible.
Key Information You’ll Get
When you perform a WHOIS Lookup using HasheTools, you’ll receive:
- Domain Owner: registrant or organization name (if public)
- Registrar Information: the company that manages the registration
- Creation, Update, and Expiry Dates: track domain lifecycle
- Nameservers: current DNS servers managing the domain
- Domain Status: active, pending delete, or client hold
- RDAP Record Link: when available, for additional verification
Domain Privacy and Data Protection
Due to privacy laws like GDPR, some domain owners choose to mask their personal information.
When privacy protection is enabled, you may see a proxy email or registrar’s contact instead of the actual owner.
HasheTools WHOIS Lookup fully complies with ICANN and GDPR guidelines, ensuring data is displayed safely and ethically.
