Questions about WHOIS

What's the difference between WHOIS and RDAP?

Both show who registered a domain. WHOIS is the original protocol and returns free-form text. RDAP is its modern, ICANN-backed successor: structured data over HTTPS with built-in privacy rules. This lookup uses RDAP wherever the registry offers it, and falls back to classic WHOIS for the rest.

Why are the owner's details hidden?

Since the GDPR, most registrars redact personal data such as the owner's name, address and e-mail. Companies sometimes keep their organization name public. To contact a domain owner, use the registrar's contact form or abuse address shown in the result.

What do statuses like "Transfer lock" mean?

They are EPP status codes set by the registrar or registry. A transfer lock is a normal safety setting that stops the domain from being moved to another registrar without the owner's approval. "On hold" means the domain was taken out of DNS and does not resolve.

How do I find out who hosts a website?

Look up the domain to see its name servers (often they name the DNS or hosting provider), then look up the website's IP address to see the network and organization it belongs to.
