A cable modem both accepts DHCP packets (for management of the modem) and passes DHCP packets through to the customer device.
Even if the CPE does so, which means there is no NAT, the key to update rDNS must, naturally, be contained only in DHCP reply to the CPE.
You are misunderstanding the technology. Many cable operators offer a cable modem in bridged mode so that the customer can attach his own home-router behind it. Sending keys over a medium shared between multiple customers is not safe. Cheers, Sander
