Frequently Asked Questions

What is a port number?

A port number is a 16-bit unsigned integer (0-65535) that identifies a specific process or service on a networked device. It allows multiple network services to run on a single IP address.

How are the port numbers generated?

The port numbers are generated using Faker.js library which creates random valid port numbers within the standard range (0-65535). The generator ensures all numbers are within acceptable limits.

What are the different port ranges?

Port numbers are divided into three ranges: Well-known ports (0-1023) used by system services, Registered ports (1024-49151) for user applications, and Dynamic/Private ports (49152-65535) for temporary use.

Can I use these ports for real applications?

These port numbers are intended for development and testing purposes. Before using any port in production, check if it's already in use and ensure it doesn't conflict with system or other application ports.

Are there any restricted port numbers?

Yes, ports 0-1023 are typically reserved for system services and require administrative privileges to bind to. Always check your system's port usage before implementing any port in your applications.
