What it does

ARP + Ping Discovery

Dual-method host detection catches devices that don't respond to ICMP, including IoT devices and firewalled endpoints.

Port Probing

Parallel scan of common service ports (SSH, RDP, SMB, HTTP, printing, hypervisor, NAS) with 200ms timeout per port.

Vendor Identification

MAC OUI lookup against the IEEE database identifies device manufacturers -- printers, switches, APs, IoT, and more.

Device Classification

Automatic typing based on open ports and vendor: Windows, Linux, Printer, Router, Switch/AP, Hypervisor, NAS, IoT.

Export

Export scan results as CSV or HTML report. Right-click any device to copy IP, MAC, hostname, or launch RDP/SSH/browser.

Single File, No Install

One exe, ~1.5 MB. No installer, no admin rights needed, no dependencies beyond the .NET runtime. Drop it on a USB and go.
