A system and method to filter potentially unwanted traffic from trackers, third-party cookies, malicious websites or other sources and present the aggregated results of said filtering to the VPN user. One of the embodiments enables a VPN user to opt-in or opt-out from the filtering activities while being able to access the aggregated information about filtering. In another embodiment, the user can choose to customize the filtering parameters to add or remove specific targets from the filtering policies.

A DNS server receives from a receiving email system, a DNS query for an email domain stored at the DNS server, the DNS query including identifying information of a sender of an email. The DNS server extracts the identifying information of the email sender from the DNS query and identifies one of a plurality of delivering organizations from the information. The DNS server determines whether the identified delivering organization is authorized to deliver email on behalf of the email domain. In response to determining that the identified delivering organization is authorized to deliver email on behalf of the email domain, the DNS server generates a target validation record based on the identity of the authorized delivering organization and the email domain, the target validation record including one or more rules indicating to the receiving email system whether the delivering organization is an authorized sender of email for the email domain.

A method and system for connecting a communication to a client including at a system bridge, establishing a client subscription connection with a client device; receiving an incoming communication request at the system bridge; publishing an incoming communication notification from the system bridge to the client device; receiving a client communication at the system bridge; and merging the incoming communication request into the client communication at the system bridge.

Various techniques for detecting homographs of domain names are disclosed. In some embodiments, a system, process, and/or computer program product for detecting homographs of domain names includes receiving a DNS data stream, wherein the DNS data stream includes a DNS query and a DNS response for resolution of the DNS query; applying a homograph detector for each domain in the DNS data stream; and detecting a homograph of a domain name in the DNS data stream using the homograph detector.

This application provides service obtaining and providing methods, user equipment, and a management server. The service obtaining method includes: determining, by user equipment, a first Internet protocol IP address by using a preset algorithm based on a service name of a to-be-accessed service; sending, by the user equipment, a communication data packet by using the first IP address as a destination address; and receiving, by the user equipment, the service provided by a serving-end device.

Advanced resource selection is disclosed. A request from a client to resolve an augmented domain is received at a Domain Name System (DNS) server. Information is extracted from the augmented domain name. The extracted information is used to select a particular resource from a set of resources to provide content to the client.

A method of routing a packet in a network is described. The network includes a plurality of nodes implementing Information Centric Networking (ICN) routing or content centric networking and routing. The method includes receiving the packet at a node implementing ICN routing, the packet comprising an Internet Protocol (IP) header and a packet payload, wherein the packet comprises a request packet for requesting content from the network. The method further includes extracting from the packet payload a content identifier for the requested content and forwarding the packet to a next hop node in the network based on the content identifier extracted from the packet payload.

The present disclosure relates generally to communication with payment terminals via TCP/IP protocol. Using network technology and novel processes, in particular embodiments, the present systems and methods facilitate local network discovery and communication between a payment terminal and an electronic cash register (“ECR”) via a browser. For example, in certain embodiments, the present systems and methods leverage TCP/IP network technology to securely facilitate communications between SaaS ECR software running in a browser environment and one or more payment terminals.
