Correct Answer: D
Censys.io is a powerful reconnaissance tool that scans the internet and provides detailed information about exposed services, certificates, and GeoIP data.
* Option A (WiGLE.net) #: Used for wireless network mapping, not host discovery.
* Option B (WHOIS) #: Provides domain registration information, not GeoIP or service summaries.
* Option C (theHarvester) #: Used for OSINT, mainly to collect emails, subdomains, and usernames.
