About this tool

WHOIS is the internet's phone book: it tells you who registered a domain, through which registrar, when it expires and which nameservers run it. This tool uses RDAP — the modern, JSON-based replacement for the old WHOIS protocol — via the free rdap.org bootstrap service, so results are structured and reliable. Use it to check a domain's age before trusting a shop, to see when a competitor's domain renews, or to verify your own registration. Only the domain/IP name you enter is looked up.

FAQ

Is this the same as WHOIS?

RDAP is the official modern successor to WHOIS — same registration data, in clean structured form.

Why is some data redacted?

Privacy laws (like GDPR) let registrants hide personal contact details; registrar and dates remain visible.

Can I look up an IP?

Yes — enter any IPv4 address and you get the network owner (ISP/datacenter) record.

Does this check availability?

A 'not found' result usually means the domain is unregistered — confirm at any registrar before buying.

Is my lookup stored?

Not by this site — the query goes straight from your browser to the free rdap.org service.

How accurate are expiry dates?

They come straight from the registry, so they are authoritative.
