Domain lookup (WHOIS)
Who a domain is registered with, when it was registered, and when it expires.
Name servers
Status
Looked up with RDAP, the structured protocol that replaced WHOIS. The request goes from your browser to rdap.org and on to the domain’s own registry; it never passes through our server.
أسئلة شائعة
Why is the owner’s name not shown?
Because registries mostly stopped publishing it. Since GDPR, personal contact details for domain owners are redacted by default, and what remains is the registrar, the dates, the name servers and the status codes. For a private individual’s domain there is usually no name to show at all.
What is RDAP, and why not WHOIS?
RDAP is the replacement for WHOIS. Old WHOIS runs on port 43 and returns free text that differs between registries, so it has to be scraped. RDAP returns structured JSON over HTTPS, which is why this lookup can run entirely in your browser — no browser can speak the WHOIS protocol at all.
What do the status codes mean?
They describe what may be done to the domain. Codes beginning client were set by the registrar, usually as a safeguard: client transfer prohibited is the normal lock that stops a domain being moved without the owner’s say-so. Codes beginning server come from the registry. Pending delete and redemption period mean the domain has expired and is on its way out.
Some domains return nothing
Not every registry runs an RDAP service. Most country-code domains do not, so a .vn or .de domain may come back empty even though it is registered. Generic domains such as .com, .net and .org are reliable.
