Connection mapping
NetView
Live Connection CartographyYou cannot defend what you have not named.
A self-contained Go network traffic visualization tool that runs locally, opens a browser dashboard on a random localhost port, and exports graph/session data.
Plain English
NetView captures packets on a selected adapter and draws a live graph of IP nodes, links, protocol colors, MAC addresses, and active connection groups.
What it teaches
- live connection mapping
- device identification by IP and MAC
- protocol awareness
- chatty device triage
Use when
- You want a live visual map of adapter traffic
- You need to identify a chatty source device
- You need JSON, CSV, or PNG export of the current session
What it observes
- Unique IP nodes
- Active sessions
- Protocol-colored links
- Packet counts grouped by source IP
Requirements
- Windows
- Npcap driver from the Nmap Project
- Administrator Command Prompt or PowerShell
- Modern browser
Manual-backed details
- Nodes represent IP addresses; links represent active communication sessions.
- Hovering over a node shows IP and MAC address for device identification.
- Controls include adapter switching, IP search, reset graph, and JSON/CSV/PNG export.
Next step
Install Npcap, run NetView.exe as Administrator, open the printed localhost URL, and inspect graph nodes plus the source-grouped side panel.
