Domain registration, registrar & expiry details
A WHOIS lookup queries public registration databases to retrieve ownership and administrative information about a domain name or IP address. When you register a domain, your registrar submits contact and technical details to the appropriate registry (such as Verisign for .com or PIR for .org). Our tool retrieves this data using RDAP (Registration Data Access Protocol), the modern replacement for the legacy WHOIS text protocol, which provides structured, machine-readable results.
WHOIS data typically includes the registrar name, domain creation and expiration dates, name servers, registrant contact information (if not privacy-protected), and domain status codes. This information is useful for verifying domain ownership, investigating suspicious websites, checking domain availability and expiry, and troubleshooting DNS configuration issues.
To use this tool, enter any domain name (like example.com) or IP address in the search field. The tool will query the relevant RDAP servers and display the registration details in an organized format. You can view raw RDAP output for the full unformatted response, which is helpful for developers and system administrators who need complete protocol-level data.
WHOIS is a public directory system that stores registration information for domain names and IP address blocks. It was originally created in the 1980s so network administrators could look up who was responsible for a given internet resource. Today it serves as a transparency mechanism that helps identify domain owners, combat online fraud, resolve trademark disputes, and enforce internet policies.
A WHOIS lookup typically returns the domain registrar, registration and expiration dates, name servers, domain status codes (like clientTransferProhibited), and registrant contact details. For IP addresses, it shows the network block, the organization that owns or operates it, and the regional internet registry (RIR) that allocated the block. The exact fields vary depending on the registry and whether privacy protection is enabled.
WHOIS privacy (also called domain privacy or WHOIS proxy) is a service offered by most registrars that replaces your personal contact information in the WHOIS database with the registrar's proxy details. This prevents your name, email, phone number, and address from being publicly visible. Since GDPR took effect in 2018, many registries redact personal data by default for registrants in the EU and other privacy-regulated regions.
WHOIS records are updated by the registrar whenever a change is made to the domain registration, such as modifying name servers, renewing the domain, or updating contact details. These changes typically reflect in the registry database within minutes to a few hours. However, some WHOIS lookup services cache results, so you may occasionally see stale data. Our tool queries RDAP servers directly to provide the most current information available.
Domain WHOIS queries registries like Verisign or Afilias to find who registered a domain name, when it was registered, and which registrar manages it. IP WHOIS queries regional internet registries (ARIN, RIPE, APNIC, LACNIC, or AFRINIC) to find which organization has been allocated a specific IP address block, the network range, and abuse contact information. Both use the same underlying RDAP protocol but query different databases.
