How WHOIS Lookups Work
Registry Query
We query the central registry database (e.g., Verisign for .com) to find the authoritative registrar.
Registrar Query
We then query the specific registrar's WHOIS/RDAP server to get the detailed owner and status data.
Parsing Data
Raw text data is parsed and formatted into an easy-to-read, structured card for you.
Frequently Asked Questions about WHOIS
What is WHOIS?
WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system. It provides essential information like expiration dates and registrar contacts.
Why is the owner information hidden?
Due to modern privacy laws like the GDPR (General Data Protection Regulation), most registrars now automatically redact personal information (name, address, email, phone number) from public WHOIS records to protect the domain owner's privacy. You will usually see "REDACTED FOR PRIVACY" instead.
What is the difference between WHOIS and RDAP?
RDAP (Registration Data Access Protocol) is the modern successor to WHOIS. Unlike WHOIS, which relies on text-based port 43 queries, RDAP delivers data securely over HTTPS in a structured JSON format, natively supporting internationalization and granular access control.
