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.
