Random Port Generator
What are network ports?
A network port is a 16-bit numeric identifier (0-65535) that allows devices to differentiate between multiple services or simultaneous connections. Ports 0-1023 are "well-known" and reserved for standard services.
Port categories
- Well-known (0-1023): system services like HTTP, SSH, DNS
- Registered (1024-49151): applications like databases, Docker
- Dynamic/Private (49152-65535): ephemeral client connections
