Overview

This node retrieves Whois data for a specified domain or URL. Whois data provides detailed registration information about internet domains, such as registrant contact details, domain creation and expiration dates, and registrar information. This node is useful for scenarios like domain research, cybersecurity investigations, brand protection, or verifying domain ownership.

For example, you can input a domain like "example.com" to get its Whois record, which helps identify the owner or check domain status. It supports extracting the domain from a full URL automatically and following HTTP redirects before querying Whois servers.

Properties

Name Meaning
Target Domain / URL The domain name or full URL to query Whois data for.
Options A collection of optional settings:
- Extract Domain Whether to extract just the domain part from the provided URL (true/false).
- Follow Number of times to follow HTTP redirects before querying Whois (number).
- Verbose Whether to show verbose results with additional details (true/false).
- Put Result in Field The name of the output JSON field where the Whois data will be stored (string).

Output

The node outputs an array of items, each containing a json object. Inside this object, there is a field (default named "whois", customizable via options) that holds the Whois data retrieved for the target domain.

The Whois data includes typical domain registration details returned by the Whois server, structured as JSON. This may include registrant info, domain status, creation and expiry dates, and registrar details.

No binary data output is produced by this node.
