SYSTEM AND METHOD FOR SUPPRESSING DNS REQUESTS

摘要

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.

1. A method for domain resolution suppression, the method comprising:
intercepting from an application executing on a computing device by a module executing on the same computing device, a domain resolution request including a domain name, the domain resolution request addressed to a first external server; suppressing, by the module, transmission of the domain resolution request to the external server; returning, by the module to the application, a pseudo internet protocol (IP) address as a response to the domain resolution request; and storing, by the module, an entry mapping the pseudo IP address to the domain name of the domain resolution request.
