About this tool
Whois is the public directory of domain and IP registrations. For a domain it tells you who the registrar is, when the name was created, last updated and when it expires, which status locks are set and which name servers are authoritative. For an IP address it returns the network block, its name and the organisation that holds the allocation at the regional registry.
The tool runs the Whois query from our probe server, parses the common fields into a readable summary and keeps the raw response for the details that vary from registry to registry. It is the fastest way to check if a domain is about to lapse, to find the right abuse contact, or to confirm when a suspicious site was registered.
What this tool gives you

Registrar, creation, update and expiry dates, status codes and name servers.
IP address Whois
For IPs you get the network name, address range and the organisation that holds the allocation.
Raw record
The unmodified Whois response for everything the summary does not cover.
Frequently asked questions
Why is the registrant hidden?
Since 2018 most registries redact personal data under GDPR, and many owners use privacy services. Dates, registrar and name servers are still public.
What does clientTransferProhibited mean?
It is a lock set by the registrar that blocks transfers to another registrar. It is normal and protects the domain against hijacking.
Why does the record say "No match"?
Either the domain is not registered, or the TLD uses a Whois server that was not reachable. Try the registrable domain without subdomains.
Can I look up a subdomain?
Whois works at the registrable domain level. Entering blog.example.com returns the record for example.com, because subdomains are not registered separately.
