A key example from its manual shows a page called sample.htm that uses HTML frames to load the lvappl.htm file, which then loads the Java viewer:
Shodan is a search engine specifically designed for discovering internet-connected devices. Its purpose is far more aligned with security research, allowing you to search by device type, operating system, or even specific vulnerabilities in a controlled and academic manner. Unlike Google, which indexes web content, Shodan actively scans the entire IPv4 address space for banners and metadata from all types of connected devices, from webcams to industrial control systems. While Shodan also raises privacy concerns, it is the standard professional tool for this type of research. inurl lvapplhtm link
