Frequently Asked Questions

What is a Random Port Generator? expand_more
A Random Port Generator creates random network port numbers within the valid range of 0 to 65535. These port numbers are useful for testing server configurations, development environments, database seeding, and educational purposes.
What is the valid port number range? expand_more
Network port numbers range from 0 to 65535. Ports 0–1023 are well-known ports reserved for common services (HTTP, FTP, SSH). Ports 1024–49151 are registered ports. Ports 49152–65535 are dynamic or private ports.
How many ports can I generate at once? expand_more
You can generate between 1 and 50 random port numbers at a time. Each port is independently generated as a random number between 0 and 65535.
Are the generated ports guaranteed unique? expand_more
Each port is independently and randomly generated. While duplicates are statistically unlikely with small counts, there is no deduplication applied. For guaranteed uniqueness, generate a few extra and remove any duplicates manually.
Is this tool free and private? expand_more
Yes, the Random Port Generator is completely free and runs entirely in your browser. No data is collected or transmitted to any server.
