nifa

Cross-platform network inspection tool.

It is designed for Linux, macOS, and Windows with a consistent command surface:

nifa <sub-command> [options]

With no sub-command (nifa), it shows the primary network interface summary.

Principles

• Read-only only: no mutation commands
• Tree-first output (tree default)
• Structured output for automation (json / yaml)

Supported Platforms

• Linux
• macOS
• Windows
