Data Source | Description | Characteristics |
|---|---|---|
WHOIS | Traditional domain lookup protocol | Older format with less structured data |
RDAP | Registration Data Access Protocol | Modern API-based format with structured JSON responses |
RDAP is gradually replacing WHOIS and provides more structured, machine-readable data.
Use Case | Purpose |
|---|---|
SEO | Analyze domain age and history |
Domain Purchases | Check expiration dates and registrar information |
OSINT | Investigate infrastructure and domain relationships |
DevOps | Verify DNS settings and nameservers |
Cybersecurity | Analyze suspicious domains |
Some registrars hide registrant information
Certain WHOIS servers limit the number of queries
Not all TLDs return the same set of data
RDAP support varies between registrars
WHOIS data may not update instantly
WHOIS and RDAP provide domain registration information, but they do not verify the actual owner of a website or company.
WHOIS and Registration Data Access Protocol (RDAP) checks provide complete information about a domain, including registration date, owner details, and contact information. This tool is useful for website analysis, domain selection, and identifying fraudulent resources.
The tool works with both WHOIS and RDAP (Registration Data Access Protocol) queries, providing the best possible information on domain registry data in real time.
WHOIS/RDAP records help determine when a domain expires, who the registrar is, and which company owns it. This is especially important for businesses involved in purchasing or monitoring domain names.
A WHOIS query provides domain registration data, including registrant contact information, registration and expiration dates, name servers, registrar information, and domain status.
Privacy protection services hide personal information to prevent spam and identity theft. GDPR and other privacy laws also restrict public access to registrant data to protect privacy.
The accuracy of WHOIS data depends on the registrar and registrant. While registrars are required to maintain accurate records, some information may be outdated or protected by privacy services.
WHOIS data can be used for legitimate purposes such as domain research, security investigations, and business intelligence. However, adhere to privacy laws and do not use it for spamming or harassment.
WHOIS is a classic protocol for obtaining domain information: registration dates, registrar, and contact details. RDAP is its modern alternative, which returns structured data in JSON format, supports multilingual responses, and more robust security mechanisms. Our tool works with both WHOIS and RDAP to provide the most accurate and up-to-date results.
These statuses indicate that the domain has been suspended and will not resolve. 'clientHold' is typically imposed by the registrar, while 'serverHold' is imposed by the registry. Both statuses prevent the domain from being accessed, often due to billing issues, disputes, or abuse.
A WHOIS query on an existing domain will provide registration data. If the domain is not registered, the query will typically indicate its availability, or you can use a domain availability checker.
Name servers indicate which servers are responsible for translating a domain name into an IP address, directing traffic to the correct hosting server. They are essential for website operation.
