Overview
The WHOIS Lookup tool retrieves registration information for domains and IP addresses from internet registrars, providing ownership details, contact information, and administrative data. WHOIS Lookup is a utility tool: it queries public registration databases. It does not add data to your Attack Surface and does not generate findings. Results are displayed as raw WHOIS output.Supported targets
| Target type | Examples |
|---|---|
| Domain | example.com, corp.example.org |
| IP address | 192.168.1.1, 8.8.8.8 |
