Registry discovery and public data
The checker uses IANA’s RDAP bootstrap registry to select the HTTPS service for a top-level domain. It requests the registered domain and displays selected public fields: registrar, registration events, status and nameservers. It does not display registrant contact details or attempt to bypass privacy redaction.
Understanding dates and status
A registration event records when a domain was created; expiration and update events describe other lifecycle changes. Registry and registrar dates can differ, particularly during renewal or grace periods. Status values such as clientTransferProhibited describe registry/registrar controls and do not directly indicate website uptime. Check with your registrar before relying on a date for renewal decisions.
When a lookup is unavailable
Use the registered domain rather than a hostname such as www.example.com. Some top-level domains do not publish a usable HTTPS RDAP service, and services may rate-limit requests. For safety this tool does not follow redirects or registrar referrals automatically. A missing record is not a guarantee that a domain is available to purchase. Check availability and renewal details with your registrar.
