En este articulo, presentamos y analizamos los principales factores que impulsan el cambio de los resolutorios de DNS públicos y la evolución de los protocolos de resolución de DNS. Examinamos los aspectos de seguridad y residencia de estos cambios.

 In the DNS resolution market there is a shift towards large-scale public DNS resolvers, such as Google, Cloudflare and Quad9, using new DNS resolution protocols like DoH and DoT. These encryption protocols mean that there is an inflection point where changes are being made in DNS settings, consciously by the user or by the service provider within the applications or operating system during upgrades. This brings an opportunity to change not only the protocol itself, but the server from which answers are obtained. This means that DNS queries, which are critical and sensitive, are starting to be handled with different protocols and by different entities that are often based in a different country or even continent than the user.
