If a matching FQDN is not found in a local database, the DNS query is allowed to proceed from the DNS resolver device to a cloud DNS resolver, the IP and MAC address of the client computing device are logged and mapped to the local database, the reputation information related to the FQDN is requested from a cloud FQDN server, and if the reputation information indicates that the FQDN should be blocked, the local database is updated with the reputation information and further queries to the FQDN are blocked.
