Network Scanner

NetworkScanner is a desktop application that scans a given IP range to check each host's liveness (Ping), open TCP ports, MAC address / vendor, and hostname, saves the results to CSV, and optionally uploads them via FTP. It flags suspicious open ports by matching them against known reserved and backdoor (trojan) port lists, and can run scans automatically on an hourly schedule.

It ships two UIs — a Windows-only WPF build and a cross-platform Avalonia build (Windows / macOS / Linux) — plus a headless CLI (netscan), all sharing the same NetworkScanner.Core scan engine. The UI is available in English (default) and Korean.
