Features

Everything a LAN admin needs, offline.

Scan the network, map devices, track ports, plan IP/VLAN and keep configs — a complete visual LAN operations workspace.

Multi-threaded CIDR Scan

Fast ping + ARP probing over a whole subnet with configurable concurrency and timeout.

Live Host List

IP, MAC, hostname, vendor, latency and open ports with green/grey online states.

Port Scan

TCP connect probing across a custom port range with service-name resolution.

ARP Discovery

Read the local ARP table and identify device vendors by OUI.

Continuous Monitoring

Background rounds with pop-up + log alerts when hosts go up or down, plus threshold alerts that open fault tickets automatically.

Export & Logging

CSV and HTML exports of every table, plus a live scan log you can clear or export.

Config Backup

Keep device configs with version and content — view, compare versions, import and export from one place.

Topology & Sample Data

Place devices on a topology canvas with links, or load built-in demo data — continuous discovery incrementally merges new devices and links.

Threshold Alerts

Latency, packet loss, jitter and bandwidth thresholds — a breach raises an alert and opens a fault ticket automatically.

Network Quality

Monitor packet loss and jitter over time so you can spot degradation before users feel it.

Alarm Notifications

Push alerts out by email and Webhook so the right people react even when they are not at the console.
