Network Scanner Agent (IP-Based Discovery)

Product: NEXTMEGABYTE (Greenitco ITAM) · Module: IT Asset Management (ITAM) · Audience: Administrator

The network scanner agent finds devices on your network, including IoT devices, printers, cameras and network equipment, using protocols such as SSH, SNMP, Telnet and HTTP. It records devices with limited (basic) information. It helps administrators monitor network health, detect unknown or unauthorized devices and track changes over time.

What the scanner collects

  • IP address
  • MAC address
  • Hostname
  • Vendor (device manufacturer)
  • Operating system type

How it works

  • It is installed on a Windows computer with an .msi installer.
  • It runs in the background as the Windows service NetworkScannerService.
  • It scans the network automatically every 5 hours.
  • It saves the results to a text file.
