Methods and systems are disclosed for discovery and assignment of privacy-protecting proxies/relays in a network. As an example, a gateway device located at a premises may send a request for data indicating one or more privacy-protecting proxies (PPPs) available to the gateway device, to a network device located external to the premises. The gateway device may select a PPP from the one or more PPPs available to the gateway device based on one or more predetermined criteria useful for selecting a PPP. The selected PPP may be assigned to a user device located at the premises by the gateway device. The assignment may be based on the selected PPP being trusted. Data associated with the user device may be routed via the assigned PPP. If the selected PPP is untrusted, data associated with the user device may be routed without using the selected and assigned PPP.

Discovery and assignment of privacy-protecting relays in a network

A system, device and method to securely notify a user of a compromise of a device are provided. The system, device and method may include a detection device adapted for determining a compromise of the device communicatively coupled to the first path, a user database including at least information regarding the device and other devices associated with the user, and the secure signal path to at least one of the other devices.

Secure notification on networked devices

Provided herein are methods and systems for improved domain name system (DNS) security. A computing device of a DNS, such as a recursive DNS server, may cache previously processed (e.g., resolved) DNS requests. The DNS cache may be a target for cache poisoning and other cache manipulation attacks. The methods and systems described herein may employ artificial intelligence, machine learning, and/or pattern recognition techniques to provide improved security for the DNS cache.

Systems and methods for improved domain name system security

Methods and systems are described for voice over packet communications.

Physical location management for voice over packet communication

Determining a location of a device for calling via an access point

Secure notification of networked devices

Methods and systems for facilitating a voice over packet (VoP) call involving a VoP device are disclosed.

Methods and systems are described for determining a physical location for a voice over packet (VoP) device engaging in voice communication via an access point. Associations between one or more physical locations and access points may be stored in a profile associated with the VoP device or a user. If the VoP device is connected to a particular access point, the profile and associations may be used to determine a current physical location for the VoP device, and for voice communications involving the VoP device.

Methods and systems are described for determining a physical address for a device connected to a network via a network access point. Associations between one or more physical addresses and network access points may be stored in a profile associated with the device. If the device is connected to a particular network access point, the profile and associations may be used to determine a current physical address for the device.

Locating a voice over packet (VoP) device connected to a network

Methods and systems are described for determining a physical address for a device connected to a network via an access point. Associations between one or more physical addresses and access points may be stored in a profile associated with the device. If the device is connected to a particular access point, the profile and associations may be used to determine a current physical address for the device.

A method and system for locating a device connected to a network by determining a current network address for the device and comparing the current network address to a network address in a user profile. If the network addresses match, the device is located based on a physical address associated with the network address in the user profile.
