Dear Wale, Hadia and Joan, Thank you for your reply ;-)! Classic DNS is processed unencrypted via port 53, end devices are assigned an IP address of a DNS resolver via DHCP, which is then used centrally by the entire operating system. However, such a process has not yet been standardized for protocols such as DoH. In addition, with DoH, applications can now use other DNS resolvers simply and in a standardized manner than the classic resolver defined in the system e.g. via browser. The current situation means that manufacturers have been going different ways to still be able to assign DoH resolvers. Google tries to upgrade an existing DNS resolver on DoH servers in Chrome and maintains a corresponding list. Microsoft also wants to proceed in a similar way for Windows. Mozilla uses a standard DoH server in Firefox for the US. With a standard, however, the assignment and use could be standardized and the DNS assignment could then also be automated relatively easily. Various ideas have now been discussed during the meeting. One suggestion provides for a separate protocol for finding appropriate resolvers (https://tools.ietf.org/html/draft-mglt-add-rdp-02). For this purpose, a list of these could be kept and queried, similar to how this already works with classic DNS. Another one is to use the DNS records directly and to store the resolver addresses there. For this purpose, so-called designated DNS resolvers are to be used, which are only responsible for certain domains (https://tools.ietf.org/html/draft-pauly-add-resolver-discovery-01). Another one is that every website simply specifies its preferred server in an HTTP header, which should then be used by clients proposed by Google and Cloudflare(https://tools.ietf.org/html/draft-schinazi-httpbis-doh-preference-hints-02). Finally, another one is based on Enrollment over Secure Transport (https://tools.ietf.org/html/rfc7030) to roll out your own certificates to clients in the network (https://tools.ietf.org/html/draft-reddy-add-iot-byod-bootstrap-00). Have a great day! Best, Matthias _________________________ Ing. Mag. Matthias M.

One major factor the IETF's Adaptive DNS Discovery WG may watch out for, as it evolves is the CDN (Content Delivery Network). It has gained so much attention because the majority of web traffic is served through CDNs.

I can highly recommend to check out this forum even if it is very technical - it helps to get the bigger picture of the Internet ecosystem ;-)! Have a nice evening!
