Description (partial)

DHCP server continues to lease IP addresses in response to the restricted CPE's requests which are made through the CMTS. The TLV35 and 63  settings are made in cable modem's configuration file. The restricted CPEs do not get the assigned addresses.

This occurs when you enable TLV35/63 feature (limiting CPE IP/IPv6 addresses) in the configuration file of the cable modem.
