Abstract
An example method for determining domain name system (DNS) forwarding rules is provided. The method includes training a machine learning model to generate recommended DNS forwarding rules and determine whether a DNS resolver is experiencing an DNS resolver issue. The method further includes receiving a DNS query at the DNS resolver which is one of a plurality of DNS resolvers forming a network of DNS resolvers. The method further includes identifying a chain of DNS resolvers of the network of DNS resolvers based at least in part on the DNS query and a DNS response to the DNS query. The method further includes analyzing the DNS query and the DNS response using the machine learning model to generate a DNS forwarding rule and to identify whether any of the DNS resolvers of the network of DNS resolvers is experiencing the DNS resolver issue.
