Generate Random Port

Generate fake and realistic port numbers to test network configurations, populate mock server environments, or simulate backend services in development workflows.

Free Random Port Generator

The tool randomly creates numeric port values such as 45550, 23523, and many others that resemble real-world networking scenarios used in TCP/IP systems.

You can generate up to 1000 unique port numbers in a single click and export them as CSV, Excel, or HTML files, or simply copy them to your clipboard for instant integration.

These fake ports are ideal for form validation, firewall testing, service discovery simulations, or any context where realistic but non-functional networking data is needed.

All generated port numbers fall within valid numerical ranges, helping you test edge cases, routing rules, or security policies without exposing real ports or services.

The tool is completely free to use and requires no sign-up. Just click, generate, and add mock port numbers to your projects in seconds.
