Automatic discovery for full-context visibility

Discover and identify every device, new or existing, and its properties to keep your network view accurate, always up to date, and free of blind spots.

Network device discovery is the automatic detection, identification, and inventory of every device connected to a network. Domotz performs continuous Layer-2 and Layer-3 discovery, identifies devices by MAC address, and maps live topology across 40K+ networks in 190 countries — free until you choose to actively manage a device.

The Domotz difference

  • Layer-2 and 3 scanning for improved device identification.

  • Automated real-time network topology mapping.

  • Discover every device including IoT and OT technology.

You can’t manage what you can’t see. Blind spots put network and device performance at risk.

Domotz gives you full-context visibility into every connected device across every site.

Discover every connected device in real-time

Networks are more diverse and distributed than ever before. Limited visibility leads to missed issues, slower response times, and costly downtime.

When you eliminate blind spots, you stay ahead of issues and deliver better service. Domotz gives you complete visibility so you can:

  • View every connected device, across every site, in a single view.
  • See every network, functional, and cloud-connected asset.
Identify every device with Layer-2 and 3 scanning

Identify every device with Layer-2 and 3 scanning.

Without accurate device identification, blind spots emerge that make troubleshooting more difficult and disrupt service.

Domotz identifies every device on your network, giving you a complete, real-time view of what’s connected:

  • Runs both Layer-2 and Layer 3 scans to detect devices by MAC address.
  • Captures key details like manufacturer, model, and device type.
  • Updates in real time as devices appear, disappear, or change IP addresses.
  • Let’s you search and filter to find any device.
Map every device and connection with interactive Network Topology

Map every device and connection with interactive Network Topology.

Trying to trace devices and their connections without a clear map feels like flying blind.

Domotz gives you the all-seeing eye your network needs (no dark towers required) to resolve issues faster and prevent downtime:

  • Live layer-2 topology visualizes every device connection.
  • Trace switch ports and follow traffic paths.
  • Instantly locate physical connection points.

Managing IT assets across your organization or client networks is complex, time-consuming and hard to scale. Manual tracking and inventory results in outdated and inconsistent spreadsheets, blind sports, and missed issues.

Domotz automates asset inventory, so you don’t have to track devices manually.

  • Automatically discover, categorize, and monitor the performance of every connected device in real time.
  • Access a searchable inventory of everything from switches and firewalls to IoT and physical security devices, all in one unified view.

Before Domotz, we had no idea what was plugged into our networks. Now, we see everything across 45 sites. We’ve even discovered rogue devices and hidden switches that had been forgotten in ceilings for over a decade.

FAQ

Frequently asked questions

What IT teams and MSPs ask about discovering devices and mapping networks with Domotz.

  • What is network device discovery?
    Network device discovery is the automatic detection, identification, and inventory of every device connected to a network. Domotz performs continuous Layer-2 and Layer-3 discovery and identifies every device by MAC address — not IP — so devices don't vanish or duplicate on DHCP churn.
  • How does Domotz discover devices on a network?
    Domotz runs both Layer-2 and Layer-3 scans, captures key details like manufacturer, model, and device type, and updates in real time as devices appear, disappear, or change IP addresses. You can search and filter to find any device on the network.
  • Does Domotz support both Layer-2 and Layer-3 discovery?
    Yes. Domotz combines Layer-2 (MAC-level) and Layer-3 (IP-level) scanning so you get an accurate, real-time inventory across multiple VLANs and /22 subnets — including IoT and OT devices traditional IT tools often miss. See Multiple VLAN Support for details.
  • Can Domotz map network topology automatically?
    Yes. Domotz builds a live, interactive Layer-2 network topology map that visualizes every device connection, traces switch ports, follows traffic paths, and locates physical connection points. See Network Topology Mapping.
  • How much does Domotz cost per device?
    Domotz costs $1.50 per managed device per month. Device discovery itself is free — you see every device on a network at no cost and only pay for the devices you choose to actively monitor and manage.
