📇 WHOIS Lookup
Registration details, registrar, key dates and status for any domain.
What a WHOIS lookup shows
Every registered domain has a record at its registry: when it was registered, when it expires, which registrar manages it, which nameservers it uses, and what status codes protect it. A WHOIS lookup reads that record. This tool uses RDAP, the modern, structured replacement for the old port-43 WHOIS protocol, querying the registry that actually runs the domain's extension, so the answer is the authoritative one rather than a copy from a reseller database. One honest exception: a few registries, .pk among them, do not publish through RDAP at all, and for those this tool says plainly that it cannot check, rather than guessing that a domain is free.
The three jobs people use it for
- Checking expiry, the single most valuable use. Domains lost to a missed renewal are a constant, expensive accident; the record shows the exact date and how many days are left.
- Checking availability properly, if a registry has no record, the name is almost certainly free to register, which our Domain Availability Checker then confirms across extensions.
- Verifying a transfer or a seller, registrar and status codes (the "client transfer prohibited" style locks) tell you whether a domain can actually move, and whether the story you are being told matches the record.
Frequently asked questions
Why is the owner's name hidden on most domains?
Privacy protection. Since GDPR and similar laws, most registrars redact the registrant's personal details by default, and many sell or include a privacy service that replaces them entirely. Hidden details are the normal, healthy state of a modern domain.
What do status codes like "client transfer prohibited" mean?
They are locks. "Transfer prohibited" means the domain cannot move to another registrar until the lock is lifted, which protects against theft. "Delete prohibited" and "update prohibited" work the same way for deletion and changes.
A domain shows as expired. Can I register it now?
Not yet. Expired domains pass through grace and redemption periods, often 30 to 75 days, during which the original owner can still renew. Only after those periods does the name drop and become available to everyone.
Why do some country domains return no result?
A few country-code registries still do not publish RDAP or public WHOIS data. For those extensions the registry's own website is the only source, and the tool says so rather than guessing.
