Find out who a domain is registered with, when it expires and which name servers it uses, or see which network owns an IP address. Lookups are free and query the official registry and regional internet registry servers directly.
Enter a domain without “www” (example.com) or an IPv4 address.
Registrar, dates and status
See the registrar, creation and expiry dates, status codes and name servers for a domain across 186 top-level domains.
Who owns the network
Check ARIN, RIPE, APNIC and LACNIC records to see which organization an IPv4 address is assigned to.

The public facts behind a domain
Every registered domain has a public record held by its registry. A WHOIS lookup shows which registrar manages it, when it was created and when it expires, its status codes and the name servers it points to. Owner contact details are often hidden for privacy, but the registrar’s abuse contact is usually listed.

ID Protection for your domains
If your own domain shows your name, home address, email and phone number in WHOIS, anyone can use them for spam, scams and sales calls. ID Protection replaces those details with private contact information, while mail sent to the domain’s contact address still reaches you.
WHOIS is a long-standing public directory of who has registered a domain name or been assigned a block of IP addresses. Registries and regional internet registries run WHOIS servers that answer these lookups.
Since GDPR, most registrars redact personal contact details by default, and many owners add a privacy service such as ID Protection. You will usually still see the registrar, dates, status and name servers.
RDAP (Registration Data Access Protocol) is the newer, structured replacement for WHOIS. When a WHOIS server gives no usable answer for some domains, this tool falls back to RDAP.
Some country-code domains have no public WHOIS server, and some registries limit how many lookups they answer. Check the spelling, leave out “www” and try again in a minute.
Not yet. The tool currently accepts domains such as example.com or example.co.uk and IPv4 addresses such as 8.8.8.8. For a subdomain, look up its main domain.
Check its expiry date in the results; it may become available later. Or try another extension, and register it with us when you find one that is free.
