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.

The present disclosure discloses a method and network device for home VLAN identification for roaming mobile clients. Specifically, the disclosed method and system detects that the mobile client has roamed away from a first network to a second network, maintains a mapping between a virtual local area network (VLAN) corresponding to the mobile client and a tunnel corresponding to a foreign agent in the second network, and forwards packets to or from the mobile client on the VLAN based on the mapping between the VLAN and the tunnel via which the packets are received. Therefore, the disclosed method and system allows for identification of home VLANs for roaming mobile clients without merging VLAN policy configurations at the home agent and the foreign agent.
