About WhoisOne

WhoisOne is a fast, lightweight and privacy-focused tool for performing WHOIS, RDAP, DNS, IP geolocation and Reverse IP lookups.

Our service is built entirely on officially supported Internet protocols, including:

• WHOIS protocol (RFC 3912)
• RDAP (Registration Data Access Protocol)
• DNS lookups through standards-compliant resolvers
• IP Geolocation APIs
• Reverse IP using third-party security datasets

We do not scrape registrar websites or use copyrighted data. All information is obtained legally through public internet protocols and licensed APIs.

Our Mission

To provide a clean, modern and ad-supported alternative to older WHOIS lookup sites, with an easy-to-use interface, a public API, and a focus on speed and accuracy.
