Abstract
A computing device includes a processor storing a mapping relationship of MAC addresses, IP addresses and device identifiers of client devices, and a network interface. The network interface receives dynamic host configuration protocol (DHCP) requests from, and transmits IP addresses to client devices. The processor, in response to receiving a DHCP request, determines if an IP address has been generated for the client device. The processor assigns the IP address to the client device in response to determining that the IP address has been generated for the client device; and obtains a device identifier from the client device in response to determining that the IP address has not been generated. The processor generates an IP address for the client device, establishes a mapping relationship of the MAC address and device identifier of the client device with the generated IP address, and assigns the generated IP address to the client device.
