# nifa [![Crates.io][crates-badge]][crates-url] ![License][license-badge]
Cross-platform network inspection tool - a modern, read-only alternative to classic network commands.

## Features
- List all network interfaces with detailed information
- Inspect a specific interface with full metadata (addresses, DNS, gateway, speeds, flags, stats)
- View routing tables (IPv4/IPv6)
- View neighbor table (ARP/NDP) with optional vendor (OUI) lookup
- Inspect open TCP/UDP sockets with process association
- Monitor live per-interface traffic statistics in a TUI
- Fetch your public IPv4/IPv6
- Display OS, kernel, proxy, permission capabilities, and default interface info
- Export view as JSON/YAML for automation

## Supported Platforms
- **Linux**
- **macOS**
- **Windows**
