Network device discovery
Plug a USB-to-Ethernet adapter into your phone, connect it to your local network and see what is on it: PLCs, switches, printers, cameras, workstations… A field tool for technicians and network administrators.
The adapter listens to the network without transmitting anything. Reads ARP, DHCP, LLDP and CDP, mDNS, NetBIOS and SSDP/UPnP announcements.
Identify the switch you are connected to (name, port, VLAN) and the active subnets.
Search for devices in an IP range you choose (ARP then ping), with each device's response time.
List a device's open TCP ports and the common services they match: HTTP, SSH, Modbus, PROFINET, EtherNet/IP, OPC UA…
IP address, MAC address, vendor, announced name and model, time since the last frame.
Share the device list as CSV with the app of your choice.
Monospaced IP and MAC addresses, identified vendors, light or dark theme following your phone. Interface in French and English.
Connect the USB-to-Ethernet adapter directly to your phone.
Connect the adapter to the local network you want to inspect, or directly to a device you want to analyze.
Detected devices appear as announcements are received.
