+
+**Network type**: Shows which network type the device belongs to. For example, Thread or Wi-Fi.
+
+**Device type**: There are 4 device types:
+
+- **End device**: End device that always keeps its radio on. Typically these devices are not battery-powered.
+- **Sleepy end device**: non-routing end device. Normally sleeping, wakes on occasion to check for messages. Typically battery-powered.
+- **Routing end device**: End device that always keeps its radio on and can route traffic for other, routing and non-routing end devices.
+- **Bridge**
+
+**Network name**: Name of the network the device joined when it was commissioned.

+**IP addresses**: Typically more than one IPv6 address is shown: link local, unique local, and global unicast. In some cases a device also supports IPv4. In that case there will also be listed an IPv4 address here.

 ## Experiment with Matter using a ESP32 dev board
 
 You do not yet have any Matter-compatible hardware but you do like to try it out or maybe create your own DIY Matter device? We have [prepared a page for you](https://nabucasa.github.io/matter-example-apps/) where you can easily flash Matter firmware to a supported ESP32 development board. We recommend the M5 Stamp C3 device running the Lighting app.
