Description
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.
