Ubuntu 18.04. DHCP server with static assignments. When a new device comes online, it gets a dynamic assignment. I take the info, and create a static assignment for that HW address. I delete the dynamic lease, expecting the static assignment to take over. But the server continues to ack the device request for its old address. How do I force it to assign the new static address? I have tried "arp -d ipaddress" and it just reassigns it again. I turn the DHCP server off, delete the arp, turn server back on, and immediately see

and the device is back online again with the wrong IP. I know I can force power off the device, but these devices are 30 miles away!
