Windows desktop network scanner. Pings every host in one or more IPv4 subnets, resolves hostnames and MAC addresses, and shows live latency statistics in a dark, table-focused UI. Built with C# / WPF on .NET 8, ships as a single self-contained exe.
- Two-phase scan: fast discovery sweep, then a configurable number of analysis pings per device — devices join the run the moment they answer
- Known devices appear instantly at scan start with their stored hostname and MAC; live results replace the stored values during the run
- Devices that just dropped offline get a quick ping burst, so short dropouts recover within seconds; offline IPs keep being rechecked during the run
- Hostname/MAC resolution over several techniques in parallel (ARP, reverse DNS, mDNS, NetBIOS); the first result shows immediately, better ones replace it
- Latency table with min/avg/max/last, heatmap colors, best/worst markers and a totals row; edit hostnames and group colors right in the table
- Up to ten latency history graphs (any device or the network average), per-network mini graphs, plus an internet latency panel with its own totals and graph — all with time markers and a configurable window
- Smooth under load: the logo animation has its own render thread and the graph math runs on a worker thread
- Pin IPs from the table or the settings — pinned entries carry an optional name and color that show up everywhere
- Subnets, pinned IPs and internet hosts managed as colored bubbles in the settings
- Device grouping by MAC vendor and hostname prefix, gateway highlighted
- Known-devices database (SQLite), mergeable between instances, upgraded automatically after app updates
- TXT/CSV reports, toggled right in the sidebar with file name and size shown
- German/English UI — switches instantly, no restart; adjustable text size
- Settings save instantly, persist as a .conf you can relocate, export and import
