PROVIDING PRIVACY ENHANCED RESOLUTION SYSTEM IN THE DOMAIN NAME SYSTEM
First Claim
1. A non-transitory computer-readable medium encoded with instructions that, when executed on a processor, perform a method of minimizing the disclosure of a domain name contained in a DNS query, the method comprising:
- determining a first label and a second label associated with a domain name included in a DNS query;
querying a first nameserver for a first resource record type associated with the first label without revealing information related to the second label by removing information related to the second label from the DNS query;
receiving a response from the first nameserver, the response including the first resource record type which directs a resolver to a second nameserver; and
querying the second nameserver for a second resource record type associated with the first label and the second label.

Abstract
An apparatus and a non-transitory computer-readable medium may perform a method of minimizing the disclosure of a domain name contained in a DNS query. The method may include determining a first label and a second label associated with a domain name included in a DNS query. A first nameserver may be queried for a first resource record type associated with the first label without revealing information related to the second label by removing information related to the second label from the DNS query. A response may be received from the first nameserver, and the response may include the first resource record type which directs a resolver to a second nameserver. The second nameserver may be queried for a second resource record type associated with the first label and the second label.

10. A non-transitory computer-readable medium encoded with instructions that, when executed on a processor, perform a method of minimizing the disclosure of a domain name contained in a DNS query, the method comprising:
-
determining a first label and a second label associated with a domain name included in a DNS query; generating a false label; querying a first nameserver for a first resource record type associated with the first label and the false label without revealing the second label to the first nameserver by removing information related to the second label from the DNS query, wherein the first nameserver is a root nameserver; receiving a response from the first nameserver including the first resource record type, the first resource record type directing a resolver to a second nameserver; and querying the second nameserver for a second resource record type associated with the first label and the second label. - View Dependent Claims (11, 12, 13, 14, 15)

16. An apparatus for minimizing the disclosure of a domain name contained in a DNS query, comprising:
-
a memory; and a processor communicatively coupled to the memory, the processor being configured to; determine a first label and a second label associated with a domain name included in a DNS query; query a first nameserver for a first resource record type associated with the first label without revealing the second label to the first nameserver by removing information related to the second label from the DNS query; receive a response from the first nameserver including the first resource record type, the first resource record type directing a resolver to a second nameserver; and query the second nameserver for a second resource record type associated with the first label and the second label. - View Dependent Claims (17, 18, 19, 20, 21)
