Check domain registration details, find the registrar and expiry date, review nameservers, EPP status codes, DNSSEC status, and raw WHOIS/RDAP data.
A WHOIS lookup shows public domain registration data. Use it to check domain registration details, confirm which registrar manages the name, find the domain's creation date and expiry date, review nameservers , and inspect the raw WHOIS/RDAP record when you need the original registry response.
RDAP lookup is the modern structured version of domain ownership lookup, while traditional WHOIS records are plain text and vary by TLD. This tool checks RDAP first and falls back to WHOIS when needed, so results can include registrar details, renewal dates, DNSSEC status, abuse contacts, and EPP status codes.
The status codes (EPP codes like clientTransferProhibited ) describe domain lifecycle and security states. Transfer locks help protect a domain against unauthorized transfer, edit, or deletion. Since GDPR and registry privacy policies, many personal contact fields are redacted, but organization, country, registrar abuse contact, and technical fields may still be visible.
Use this domain WHOIS lookup before buying a domain, planning a migration, auditing domain security, or investigating a suspicious hostname. The registrar, expiration checker, transfer lock, nameservers, and raw record are often enough to spot renewal risk or ownership changes.
If the domain is registered, compare the WHOIS or RDAP result with DNS and SSL checks. Nameservers should match the expected DNS provider, DNSSEC should match your security plan, and the expiry date should leave enough time for renewal before service is at risk.
A WHOIS lookup checks public domain registration data, including the registrar, creation date, expiry date, nameservers, status codes, DNSSEC status, and any contact fields the registry or registrar publishes.
WHOIS is the older text-based registration lookup protocol. RDAP is the newer structured format used by many registries. This tool tries RDAP first, then falls back to port 43 WHOIS when needed.
Yes. When the registry publishes the data, the result shows the registrar, IANA registrar ID, creation date, last updated date, expiry date, domain age, and days left before renewal.
Many registrars redact personal contact data because of privacy laws and registry policies. You may still see organization, country, registrar abuse contact, or other non-personal fields when they are public.
clientTransferProhibited is an EPP status code that means the registrar is blocking transfer to another registrar. It is commonly used as a domain security lock against unauthorized transfer.
WHOIS and RDAP can come from different registry or registrar systems, and some fields may update at different times. RDAP is structured, while raw WHOIS records are text and can vary by TLD.
