Since it has been introduced the NAT64/DNS64 transition mechanism has reputation of method which simply works. This could change as currently used detection method, RFC7050 , for this transition mechanism doesn’t work with third party/foreign DNS resolvers. These resolvers have been lately introduced by Mozilla Firefox  with implementation of DNS over HTTPS. This paper describes problems connected with default usage of third party DNS resolvers and provides a way how to solve issues of RFC7050  with and without third party resolvers.
