Why is the owner's name hidden?

Registries redact personal contact data under GDPR and comparable privacy rules. What remains is the registrar and, usually, an abuse address that forwards to the owner.

Why do some domains return nothing at all?

Not every registry runs an RDAP service; some still answer only on port 43, the old WHOIS protocol, which a website cannot reach. We say so rather than inventing a record.

What do codes like clientTransferProhibited mean?

They are registry status codes. That one is the normal setting most registrars apply to stop a domain being moved without your say-so; each code shown here comes with a plain explanation.

Is the expiry date the deadline to renew?

It is the registry's expiry date. Most registrars add a grace period after it, but they set their own cut-off, so renew before the date rather than relying on it.

About WHOIS Lookup

Shows who a domain is registered through, when it was registered and when it expires, the registry status codes that say whether it is locked or on hold, its nameservers, its DNSSEC state and the abuse contact - with the raw record underneath if you want it.

It uses RDAP, the structured successor to WHOIS, via rdap.org. Two limits are worth knowing before you start: most registries redact the owner's name and email under GDPR and similar rules, and a number of country registries publish no RDAP service at all, in which case you get an honest "no record" instead of a made-up one.

IP addresses work too, and return the network they belong to.

How to use it

1Type a domain name or an IP address
2Press Look up - our server queries the registry
