Frequently Asked Questions

What types of port scans are supported?
The tool supports common ports (top 20), port ranges (e.g., 1-1000), specific ports (e.g., 80,443,8080), and service-based scans focusing on database and web services.
Why is this a simulated scan?
Web browsers cannot perform actual network port scanning due to security restrictions. This tool simulates realistic results for educational and demonstration purposes.
What do the port statuses mean?
Open: Service is listening and accepting connections. Closed: No service listening. Filtered: Port blocked by firewall. Timeout: No response within time limit.
How can I perform real port scanning?
Use dedicated tools like Nmap, Masscan, or Zmap from command line. Always ensure you have permission before scanning networks you don't own.
What services are commonly found on different ports?
Port 80 (HTTP), 443 (HTTPS), 22 (SSH), 21 (FTP), 25 (SMTP), 3306 (MySQL), 5432 (PostgreSQL), 3389 (RDP), and many others have standard service associations.
