Authoritative DNS servers are those that are designated by a domain name administrator to be the authoritative source of DNS information for a particular domain name. This means that the authoritative DNS server is the only server that is allowed to provide DNS information for that domain name.

An authoritative DNS server is responsible for ensuring that the DNS information for a domain name is correct and up to date. It is also responsible for resolving DNS name queries.

In order to provide the best possible DNS service, authoritative DNS servers typically use a variety of mechanisms to ensure that the DNS information they provide is accurate. These mechanisms include using data from a number of other DNS servers to verify the accuracy of the information they are providing, using static DNS data to prevent information from being corrupted, and using dynamic DNS updates to keep the DNS information up to date.
