The net object represents the Ethernet interface of your device. This object only specifies various parameters related to the Ethernet interface and is not responsible for sending/transmitting network data. The latter is the job of the sock object.
Here is what you can do with the net object:
| • | Check if the Network Interface Controller (NIC) IC is functioning properly. |
| • | Check your device's Ethernet MAC address. |
| • | Set the IP-address of the Ethernet Interface. |
| • | Set default gateway IP and the netmask. |
| • | Be notified when the Ethernet cable is plugged or unplugged and check current link status. |
| • | Be notified when data overflow occurs in the NIC. |
