Abstract: Methods and apparatus are provided for enhancing security and features during cable modem configuration. According to various embodiments, a cable network head end is configured to ensure that a cable modem subscriber registers with its assigned configuration profile. Techniques for verifying parameters in a received configuration profile, enhancing authentication, preventing access to provisioning servers, securing communications, and enhancing feature sets are provided.

Abstract: An embodiment method may comprise establishing a link layer connection to an access server, obtaining a management address, wherein the management address is at least one of an IPv6 and an IPv4 address, obtaining a TFTP server address, wherein the server address is either IPv6 or IPv4, downloading a configuration file from the TFTP server, and registering with the access server as IPv6 capable. Another embodiment may be a cable modem termination system (CMTS) comprising a port to receive downstream internet protocol (IP) traffic, a processor in communication with the port, the processor to classify downstream traffic based on fields in IP version 6 (IPv6) headers; and a radio frequency port in communication with the processor, the radio frequency port to send downstream traffic from the CMTS, wherein the processor uses a flow label as the downstream classifier so IP addresses can remain encrypted in the downstream traffic.
