KM SERVICE

Routers, PCs, printers, cameras, smart TVs, NAS drives, access points, switches: most homes and offices today have dozens of devices connected to the same network, and almost no one knows exactly how many there are, where they're physically located, or whether they're still reachable. When something stops working — the printer doesn't respond, the camera goes offline, a PC disappears from the network — you start guessing, unplugging cables at random, calling "the technician."

KNetMonitor was built to solve exactly this problem: a lightweight application that scans the local network, automatically discovers connected devices, and displays them on an interactive visual map, always updated in real time.

On startup, KNetMonitor scans the network (or networks — it can monitor more than one at the same time) by combining two complementary techniques: ARP requests, which identify each device by its physical (MAC) address, and ping, which verifies its actual reachability. The result is a reliable list of everything connected, automatically refreshed at regular intervals.

Each discovered device appears as an icon on the map — PC, laptop, switch, router, camera, or generic device — with a colored ring showing its status at a glance: green for online, red for offline, gray for unknown. No guesswork needed: if something goes offline, you see it immediately, and an optional sound alert can notify you even when you're not looking at the screen.

Automatic layout is just the starting point. Every icon can be dragged exactly where it belongs — next to the actual room where the device is located, for example — and its position is remembered. You can draw rectangular zones to visually group the devices of a department, a floor, or an area, and draw connections between devices to represent how they're actually wired: a solid line for a network cable, dashed for a WiFi connection, thicker for fiber.

The result, after a few minutes of arranging, is a network diagram that's readable at a glance — something that would normally require professional diagramming software, generated instead automatically from the real devices on your network.

Device icons are in .SVG format and can be freely added, changed, or customized — the program recognizes new icons and integrates them into both the selection menus and the map.

Double-clicking a device instantly opens its key information:

Right-clicking opens a menu with the most common diagnostic and remote administration actions:

For those managing multiple networks — a site, a branch office, a lab, a test network — KNetMonitor supports multiple profiles: each with its own configuration, devices, and map, selectable from a single startup screen. And so you don't have to rename the same devices every time they reappear on a different network, a global archive automatically recognizes previously seen devices by their MAC address, instantly recalling their name and type.

KNetMonitor runs entirely locally: no data leaves the network, no account to create, no subscription. It's available as a standalone Windows executable, ready to use on any PC with nothing to install.

Whether it's keeping an eye on a small office network, understanding what's connected at home, or finally getting a clear map of an infrastructure that's grown over the years without documentation, KNetMonitor turns an anonymous list of IP addresses into something you can actually look at, understand, and manage.
