A DNS authoritative server is a server that is responsible for the resolution of DNS queries. A DNS query is a request from a client asking a resolver for the IP address or domain name of a specific host.

The authoritative server is the authoritative source for the DNS records for the domain name. This means that it is the server that is responsible for ensuring that the DNS records for the domain name are up-to-date and correct.

Authoritative servers are important because they ensure that DNS queries are resolved correctly. If the authoritative server is not functioning properly, then DNS queries will not be resolved correctly and the clients using the DNS system will experience issues.

Additionally, if the authoritative server is down, then clients will not be able to access the DNS system at all.

Authoritative servers are usually located in the same location as the DNS root servers. This means that the authoritative server can provide information about the DNS records for the entire domain name system.

Additionally, authoritative servers are usually configured to use a secure connection to the DNS root servers. This ensures that the data that is exchanged between the authoritative server and the DNS root servers is protected.

Authoritative servers are important for the DNS system and should be maintained and configured properly. If the authoritative server is not functioning properly, then clients will experience issues and the DNS system as a whole will be impaired.
