About this tool
Whois is the oldest directory service on the internet: registries publish who holds a domain name or an IP address block, when it was registered, when it expires and which name servers answer for it. This tool runs the whois command from our servers against the correct registry and shows the raw record plus a parsed summary of the fields people look for most: registrar, dates, status codes and name servers for domains; network range, netname, organisation and abuse contact for IP addresses.
Use it to date a domain before trusting it, to find the right abuse mailbox when reporting an attack, to confirm an expiry date before a renewal, or to see which hosting company owns an address range. The Domain Age Checker is a faster option when you only need the creation date.
This is what a result looks like (trimmed):

Frequently asked questions
Why is the registrant hidden?
Since GDPR most registrars redact personal data in public whois. Company names, registrar details, dates and name servers are still visible; use RDAP or the registrar's contact form to reach the owner.
Whois for an IP shows a company I do not recognise
IP whois describes the network block, not the end user. The listed organisation is the ISP or hosting provider that was allocated the range by a regional registry (ARIN, RIPE, APNIC, LACNIC, AFRINIC).
What does "clientTransferProhibited" mean?
A registry lock set by the registrar to prevent the domain from being moved to another registrar without the owner unlocking it first. It is normal and recommended.
Can I look up a .com, .io, country-code or new gTLD domain?
Yes. The lookup follows referrals to the TLD's authoritative whois server. Some registries throttle queries, retry in a minute. Some TLDs may not have a publicly accessible whois server.
