The Modern Way to Search Domain Registration Data
For decades, the WHOIS protocol has been the standard for looking up domain name registration details. However, as the internet has evolved, so have the needs for better security, standardized data, and international support. Enter RDAP (Registration Data Access Protocol).
OneWhois™ uses the modern RDAP protocol to query registries directly, providing you with the most accurate, standardized, and up-to-date domain registration data available. Unlike traditional WHOIS, which often returns messy, unformatted text that varies by registrar, RDAP delivers responses in a secure, standardized JSON format. This means faster lookups, cleaner data, and full support for internationalized domain names (IDNs).
By using OneWhois™, you are accessing the next generation of domain lookup technology—designed for the modern web.
Frequently Asked Questions (FAQ)
What is a WHOIS or RDAP domain lookup?
A domain lookup is a query tool used to find out the registration details of a specific domain name. It allows you to check the domain's creation and expiration dates, current status, the associated nameservers, and the registrar of record.
How is RDAP different from traditional WHOIS?
While both protocols serve the same fundamental purpose—looking up domain registration data—RDAP is the modern, ICANN-approved successor to WHOIS. The traditional WHOIS protocol relies on plain text, meaning the output format can look completely different depending on which registry you query. RDAP standardizes this data, providing a uniform, machine-readable format. Additionally, RDAP offers enhanced security (operating over HTTPS), better support for non-English characters, and a secure way to provide differentiated access to registration data.
Why is some domain registration data hidden or redacted?
When you search for a domain, you might notice that the owner's name, email, or phone number says "Redacted for Privacy" or "Data Protected." This is largely due to international privacy laws, most notably the General Data Protection Regulation (GDPR) in the European Union. To comply with these data privacy regulations, domain registries and registrars automatically mask the personal contact information of the domain owner. Additionally, many domain owners use commercial "Domain Privacy" services to hide their personal details from public databases to prevent spam and identity theft.
Which domain extensions (TLDs) can I search?
OneWhois™ is designed to be one WHOIS for all domains. Our RDAP-powered search tool supports all standard Top-Level Domains (TLDs) such as .com, .net, and .org, as well as modern generic TLDs (e.g., .app, .io, .tech) and country-code TLDs (ccTLDs), provided the registry has implemented the RDAP protocol.
