As I understand an Intel vPro based computer can be powered on remotely without the use of a 'magic packet', the management controller is sitting in a low powered state listening on specific ports. Therefore I'm assuming that the management controller is sharing the IP address of the host that is shut down.
Does the management controller maintain this IP address continually renewing it after the lease expires?

Essentially AMT, the vPro feature that allows for remote power on, has its own processor. This is often called the Manageability Engine (ME). It can request DHCP addresses. At the same time, it's smart enough to know when the OS has control of the NIC. In that case, it lets the OS handle DHCP and just uses the same IP. When the OS is down (system is off, or NIC driver is not installed or failing), AMT will take over making DHCP requests as needed.
