  • Domain name system identification and attribution
    Patent number: 10645057
    Abstract: Techniques are presented herein for a DNS resolver to encode a falsified IP address with a client identifier that identifies a client attempting to access a blocked domain. The DNS resolver receives, from a client, a DNS request that contains a requested domain name and a client identifier. The DNS resolver then determines the identity of the client from the client identifier in the DNS request. The DNS resolver then applies policies for the domain name system request to determine that the requested domain name should be blocked for the identity of the client. The DNS resolver may then construct a falsified Internet Protocol address when the domain name should be blocked for the identified client, where the falsified Internet Protocol is encoded with the client identifier. The DNS resolver then sends to the client, in response to the DNS request, the falsified Internet Protocol address.
