WHOIS Lookup FAQ

What is WHOIS?

WHOIS is a query and response protocol used for querying databases that store the registered users or assignees of an internet resource, such as a domain name.

What is RDAP?

RDAP (Registration Data Access Protocol) is the modern successor to WHOIS. It delivers registration data in a structured, machine-readable JSON format and offers better internationalization.

Why is some contact information hidden?

Due to privacy laws like the GDPR, many registrars redact personal contact information (name, email, phone) from public WHOIS and RDAP records.
