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.
