We are looking into doing DHCP Option 82 for our NMS DHCP subnet for our CPE devices. If I am understanding this correctly, through this option I will be able to designate the IP address(es) that are going to be allocated behind that CPE device. This way I will only have to track MAC address of customer through my inventory and billing system. Through DHCP server, we will be able to determine which IP address is linked to specific CPE devices.
