Abstract:
A virtual private router (VPR) intercepts DNS requests and returns a pseudo IP address to the requesting application and the pseudo IP address is mapped to a domain name in the request. Requests for content including the pseudo IP address are modified to include the corresponding domain name and transmitted to an intermediary server, which resolves the domain name to a real IP address and forwards the content request. The content is received by the intermediary server, which returns it to the requesting application, such as by way of the VPR. Real IP addresses may be returned by the intermediary server such that subsequent content requests to the domain name may bypass the intermediary server. Requests for certain domains, ports, and/or protocols may bypass the intermediary server such that the VPR resolves the domain names to real IP addresses.
