Abstract
The present disclosure discloses a method and a network device for controlling DHCP pool exhaustion in dynamic network environments. Specifically, a network device determines that a client device is assigned an Internet Protocol (IP) address by a DHCP server. The network device detects that the client device is disconnected from a network associated with the IP address, for example, by receiving a de-association message from the client device; determining that a session or an entry corresponding to the client device has timed out; determining that the client device has failed to respond to one or more messages transmitted to the client device; determining that the client device has connected to another network different than said network; etc. In response, the network device then generates a DHCP release message on behalf of the client device, and transmits the DHCP release message to the DHCP server.
