Frequently Asked Questions
Does this tool run Nmap scans directly in the browser?▼
No. Web browsers cannot send raw TCP/UDP packets. This tool generates the formatted Nmap command and recommended flags for you to copy and run in your own authorized terminal environment.
What do the generated flags (-sV, -O, -Pn) do?▼
-sV enables service and version detection on open ports, -O attempts remote OS fingerprinting, and -Pn skips initial host ping discovery, treating target hosts as online.
Is network scanning authorized everywhere?▼
No. Unauthorized port scanning can violate computer crime laws and cloud provider terms. Only run scans against hosts, IP ranges, or networks you own or have explicit written permission to test.
