Which type of server should be queried to obtain the most reliable and up-to-date information about the IP address associated with a specific domain name?
Internet service provider
Non-authoritative server
Recursive server
Authoritative server
An authoritative server provides the most reliable and up-to-date information because it is responsible for storing the original and definitive records of a domain within a specific zone. Since these servers directly manage the data concerning their respective zones, the information provided is current and unaltered by external caches. Non-authoritative (cache-only) servers, on the other hand, store copies of information that might be outdated or incomplete depending on the timing and frequency of their updates.
