Domain registrar name, registration and expiration dates, name servers, DNSSEC status, and the RDAP registry where the domain is managed.
WHOIS is the legacy protocol. RDAP (Registration Data Access Protocol) is the modern replacement that provides structured JSON data and respects privacy laws by redacting personal info.
Most generic TLDs (.com, .net, .org) and many country-code TLDs are supported. Some ccTLDs may have limited data depending on the registry's RDAP implementation.
GDPR and other privacy regulations require registries to hide personal contact details. The lookup shows the registrar and public data, but personal info is masked.
