A method of initializing, provisioning, and managing a cable modem and a customer premise equipment device includes sending a customized configuration file to the cable modem. The configuration file contains service provisioning information and further includes information indicative of a network address type for the customer premise equipment device. A message is passed from the cable modem to the customer premise equipment device indicative of the network address type. The customer premise equipment device is provided with a network address in accordance with the network address type indicated in the message. In this way, the customer premise equipment device knows what kind of address to obtain, and excessive transactions are avoided.

Initializing, provisioning, and managing devices

A system for providing a Domain Name System (DNS) service may include providing an agent for installation on a subscriber device. The subscriber device may be connected to the DNS service via an entry point device. The system includes receiving, from the agent, agent data indicative of a subscriber identifier and a unique identifier associated with the entry point device. The system may then determine, based on the agent data, a current Internet Protocol (IP) address associated with the entry point device and associate the unique identifier with the subscriber identifier. The system may then dynamically map the subscriber identifier to the current IP address and provide DNS service to the subscriber device based on the current IP address.

Systems and methods for providing DNS services

A device control system is associated with individual devices connected through a network control point to a gateway and thereby to the Internet. The gateway inserts an EDNS0 pseudo resource record into an additional data section in each DNS query initiated by an individual device, the EDNS0 pseudo resource record identifying the initiating device. A dynamic policy enforcement engine in front of the DNS engine intercepts the DNS query, identifies the initiating device, and selects a policy that applies to the device. The dynamic policy enforcement engine may provide parental control and security service to the individual device by blocking the DNS query or passing it to the DNS engine according to the policy. A component that intercepts DNS queries may provide several additional types of services to the individual devices, including advertising, messaging, mobile device tracking, individual device application control, and delivery of individualized content.

System for providing DNS-based policies for devices

A system and method for provisioning network elements, such as but not limited to the type of network elements used in cable television system to facilitate subscriber access to services. The provisioning may be accomplished without communications between multiple provisioning servers. This allows the provisioning to be conducted in a stateless manner.

Method of provisioning network elements

Provided is a method for delegation of local content delivery service. The method includes receiving a Domain Name System (DNS) query from a client to resolve a domain name to a network address associated with content provider by a content provider, determining that distribution of the content has been delegated by a content provider to a local content server associated with an Internet Service Provider (ISP), and based on predetermined criteria, resolving the domain name to the local content server. The resolution can include responding to the DNS query with an answer from a caching server, and returning, to the client, the answer pointing to the local content server, wherein upon receiving the answer, the client can establish a data communication channel with the local content server. The content can be downloaded to the local content server upon a request received by a provisioning system associated with the ISP.

System for providing DNS-based control of individual devices

Provided are computer-implemented methods and systems for analyzing domain name system requests and developing profiles associated with these requests. Multiple requests received from the same internet protocol (IP) address may be analyzed to differentiate computer systems used to generate these requests, applications provided on these computer systems, and even different users. The requests are analyzed based on text string content (e.g., domain and subdomain names) and timing. One or more profiles are developed and continuously updated based on requests received from the same IP address. These profiles may be used in real time to provide feedback to the users (e.g., deliver marketing content) or for subsequent analysis of comprehensive data sets (e.g., to identify behavior patterns). For example, a profile may be used to identify a number and types of computers in the household, a number and demographic information of users, and other such identifiers.
