Desktop & Networking 2026 Own project

NetzAtlas

Desktop app for network documentation with automatic discovery — topology read live from the network instead of maintained by hand.

  • .NET 9
  • WPF
  • WebView2
  • SNMP/LLDP
  • C#

Status & progress

In progress Duration: ongoing

Completed

  • Data model & schema v1.0
  • Device inventory (type, vendor, model, IP/MAC)
  • Topology & rack visualization
  • Interface status & signal path
  • Multi-tenant per site

Open / next steps

  • Wire live discovery into the shell
  • Packaging & distribution
  • Cross-platform (Avalonia)

Starting point

Network documentation in MSP operations is manual work: topology, racks and cabling are maintained by hand and are therefore almost always out of date. Across several GDAP-managed customer environments this quickly becomes unsustainable.

Solution

A desktop application that detects the network live via the network adapter and visualizes it — instead of guessing.

  • Automatic discovery via SNMP (LLDP-MIB/CDP, ifTable), the ARP table and a targeted ping sweep — the network graph builds itself edge by edge.
  • Visualization of topology, racks and cabling including signal-path analysis (BFS) in a WebView2 interface.
  • Multi-tenant for MSP operations: a separate view per customer environment.
  • No forced elevation in the MVP: SNMP, TCP-connect scan and reverse DNS work without admin rights and without packet capture.

Result

Up-to-date network documentation at the push of a button instead of diagrams that are stale the moment they are drawn. An in-house build, tailored to the operation it serves.

Sounds like something you need too?
