Synopsis

We revisit the open DNS (ODNS) infrastructure and, for the first time, systematically measure and analyze transparent forwarders, DNS components that transparently relay between stub resolvers and recursive resolvers. We introduce DNSRoute++, a new traceroute approach that leverages the behaviour of transparent forwarders and explores interconnectivity in the ODNS.
