❓ Frequently Asked Questions

Q: What is a port number?

A: A port number is a 16-bit integer (0-65535) that identifies a specific process or service on a computer in a network. It allows multiple services to run on the same IP address.

Q: Why do I need random ports?

A: Random ports are useful for avoiding conflicts, testing applications, setting up temporary services, and enhancing security by using non-standard ports.

Q: Are the generated ports truly random?

A: Yes, our tool uses cryptographically secure random number generation to ensure unpredictable and secure port selection.

Q: Can I use system ports (1-1023)?

A: System ports are reserved for well-known services and typically require administrator privileges. Use them only if you understand the implications.

Q: What's the difference between TCP and UDP ports?

A: TCP ports are for connection-oriented communication (reliable, ordered), while UDP ports are for connectionless communication (fast, lightweight). The same port number can be used by both protocols simultaneously.

Q: How do I check if a port is available?

A: You can use command-line tools like netstat, ss, or lsof to check if a port is currently in use on your system.

💡 Pro Tips

Development: Use ports above 3000 for local development to avoid conflicts
Production: Always check port availability before deploying services
Security: Use non-standard ports for services to reduce automated attacks
Documentation: Keep track of port assignments in your infrastructure documentation
Testing: Use different port ranges for different environments (dev, staging, prod)
