All DOCSIS modems will have MAC addresses and the modem will use DHCP to get an IP address. The modem must be able to get an IP address via DHCP as part of it's boot-up sequence.
Some older modem technologies did not require the modem have a MAC address. A proprietary protocol was used between the modem and the CMTS to configure and access the modem. Note, bridges and switches will have lots of MAC addresses and very few or no IP addresses. For the most part, a modem is a bridging device.
