User identity differentiated DNS resolution
First Claim
1. A method for domain name system (DNS) resolution implemented in a computing device comprising:
- at a domain name system (DNS) resolver, receiving, from a client, a request to resolve a domain name or multiple domain names into their corresponding IP address or IP addresses, and receiving, from the said client, authentication credentials that identify the user;
choosing, based on the user identity associated with the request, one or more recursive domain name servers from a plurality of recursive domain name system (DNS) servers available to the DNS resolver;
sending the DNS request to the chosen recursive domain name system server or servers for the purpose of resolving the requested domain name or names for the said client;
returning the response or responses from the chosen recursive domain name system server or servers back to the client.

Abstract
Systems and methods for DNS resolution based on user identities are provided herein. In the DNS name resolution process, a DNS resolver can construct and send DNS queries to different DNS name servers depending on the identities of the users requesting the name resolution. One embodiment may be a DNS forwarder configured in a home router, where DNS requests from a certain user group (e.g., kids) may be forwarded to OpenDNS Family Shield, while DNS requests from another user group (e.g., parents) may be forwarded to the ISP'"'"'s default DNS servers or Google Public DNS. In another embodiment, the DNS resolver may be integrated within an authenticating proxy server, wherein the DNS resolver may use different DNS name servers to perform DNS name resolution for different users authenticated by the proxy server.

18. A system for domain name system (DNS) resolution comprising:
-
a domain name system (DNS) resolver module to receive domain name system (DNS) resolution requests from a client; an authentication module that authenticates users of clients sending domain name system (DNS) resolution requests to the domain name system (DNS) resolver; a single or a plurality of recursive domain name system (DNS) servers that the domain name system (DNS) resolver is capable of communicating with; and a configuration module comprising a set of configuration files or a database or other storage that enables one or more processors to chose, based on user identity and rules, the recursive domain name system (DNS) server or servers to use for domain name system (DNS) resolution requests from an authenticated user. - View Dependent Claims (19, 20)
