Frequently asked questions
Everything you need to know about WHOIS and RDAP lookups.
A WHOIS lookup checks domain registration information, such as registrar, creation date, expiry date, domain status and nameservers.
RDAP is a modern structured protocol for retrieving domain registration data. It is designed to replace traditional WHOIS with more consistent machine-readable responses.
If a domain expires, websites, email and DNS services connected to it may stop working. Checking expiry helps avoid accidental domain loss.
clientTransferProhibited usually means the domain is locked against transfer. This is common and often protects the domain from unauthorized transfers.
Often no. Many registrars and registries hide or redact personal contact details for privacy and compliance reasons.
No. The WHOIS Lookup tool is free and does not require signup.
