consider the open DNS server at google 8.8.8.8. It doesnt know the IP addresses of all the devices. Suppose the client makes a request goes to the resolving DNS server asking for amazon.com. It is unaware of it so it asks the root level serevrs...root servers send the request to top level domain servers (which hold the information about the .com .org .net etc..servers)..these servers gives the IP addreses of the authoritative server(for amazon)..which is under the .com domain
So it basically goes from the resolving DNS server-->rootlevelserver-->top level domain server -->authoritative servers
