Processing of all DNS requests start at the root of the DNS tree and make use of either cached data from previous requests, or by traversing the DNS tree for the missing information. When \emph{QNAME minimization} is not in use, queries forwarded to the parental nodes in the DNS tree may leak private DNS query data. In this paper we examine 31 days during the month of January 2017 of queries sent from two recursive resolvers placed in two residential networks to the DNS root server operated by \isi's, analyzing the leaked QNAMEs for an impact on the network's privacy. We then compare a few DNS privacy preserving techniques against the privacy analysis against these networks.
