Whether it "makes sense" could be debated, but that's how DHCP is defined to work. When a client request an IP address, the ack from the server that grants an address contains a "lease time". The client owns that IP address until the lease time expires or until the client sends an explicit release to the server -- the client does not lose ownership of the IP because it's been rebooted or disconnected temporarily. IMO, that does make sense. It prevents IP address churning as devices are plugged/unplugged, rebooted, moved around, whatever. If you want an address to become free shortly after a device is disconnected from the network, then you need to set your lease time to a small value. -- Grant Edwards grant.b.edwards Yow!
