For the management of devices connected to a network, relevant information about the devices and the network is required. To get this information a network scan is necessary. The usual scan process makes use of SNMP (Simple Network Management Protocol) for reading and writing of the device and network information. The case where network devices do not support SNMP is not solved until now. For such network devices, only a few details like their IP (Internet Protocol) and MAC (Media Access Control) address can be obtained by using other protocols like ICMP (Internet Control Message Protocol) or ARP (Address Resolution Protocol).
