Authoritative DNS servers are servers that are given the responsibility of managing the DNS zones for a given organization. This means that they are the authoritative source for DNS information for that organization.

Authoritative DNS servers are often used in larger organizations, as they can handle more DNS requests than a non-authoritative DNS server.

A non-authoritative DNS server simply responds to DNS requests without actually managing the zones. This can lead to issues if the non-authoritative DNS server is not able to answer a DNS request correctly.

Authoritative DNS servers are typically more reliable, as they are responsible for managing the DNS zones and are therefore more likely to be able to answer DNS requests correctly.

It is important to note that not all DNS servers are authoritative. Non-authoritative DNS servers are typically used for smaller organizations that do not need access to the authoritative DNS servers.
