摘要： A client analyzes requests for network resources to determine an IP address associated with the request, such as a destination IP address of a network packet. The client device selectively routes the request and other traffic associated with the IP address. The client device establishes a tunnel or other direct connection with a remote server. Network traffic can be selectively routed to the destination IP address associated with a resource request, or to the remote server based on the destination IP address associated with the request. The system can route client network requests to the remote server based on a category or other information associated with the destination IP address. Network packets associated with malicious or suspicious IP addresses, for example, may be routed to the remote server for performance of security features, while packets associated with other IP addresses may be directly routed to their target destination.
