Abstract: The present disclosure discloses a method and network device for adaptive DHCP assignment with VLAN pool. Specifically, a network device can assign a client device to a first Virtual Local Area Network (VLAN). The network device then detects a first DHCP Discover message, transmitted by a client device, corresponding to a first VLAN. Also, the network device determines that no DHCP offer message, responsive to the first DHCP Discover message, is transmitted to the client device. Then, the network device transmits on behalf of the client device a second DHCP Discover message for the second VLAN to a DHCP server, and receives a DHCP Offer message in response to the second DHCP Discover message. The network device then assigns the client device to a second VLAN, and subsequently transmits the DHCP Offer message for the second VLAN to the client device.
