DHCP Lease Behavior Upon Client Disconnection

If a client does not send a DHCP Release to the MX DHCP server upon disconnecting from the network, its IP address will be unavailable until the lease time expires. The MX will hold the lease, even if the node is disconnected and is no longer using the IP address.

While the lease is given out, it is visible from the DHCP live tool. More information about the DHCP live tool can be found here.
