Abstract
A network processing device is configured to receive a configuration message from a host device and forward the configuration message to a server. The configuration message can be configured to request the server assign an Internet Protocol (IP) address to the host device. The network processing device can be configured to send at least one probe message to the host device responsive to receiving the configuration message. The network processing device can be configured to determine whether the host device intends to continue utilizing a previously assigned IP address in addition to the IP address requested by the configuration message based, at least in part, on any responses to the at least one probe message received from the host device.
