To overcome this the industry actors and researchers have come up with DNS-over-Encryption which leverages already established encrypted protocols for DNS. While there have been a number of studies that measure the performance of these new protocols, most of these measurements have been done from developed countries and from university networks with robust Internet infrastructure. We still lack a global overview of how these encrypted DNS protocols perform all around the world and what are the factors which affect their performance other than the size of the network packet. This paper aims at answering these important questions while at the same time reasoning about the DNS-over-HTTPS measurements obtained. We compare the performance of DNS-over-HTTPS with the performance of legacy DNS for countries around the world to understand how the migration to DNS-over-HTTPS affects different countries and if all countries are equally affected.","abstract_html":"It has long been established that using DNS-over-UDP poses multiple threats to security and privacy ranging from Man-in-the-Middle-attacks to your ISP keeping a track of what websites you are visiting.
