Authoritative name servers are responsible for ensuring that the correct DNS records are placed for a given name. When a user types in a URL, the authoritative name server will look up the correct record for the given name and return it to the user’s computer.
If the user’s computer doesn’t have an authoritative name server configured, then it will try to contact one of the name servers that is listed in the user’s DNS configuration. If there is no authoritative name server listed, the user’s computer will use the DNS server that is closest to them.
An authoritative name server is important because it ensures that the correct records are placed in the DNS database. If there is a typo in a URL, for example, the authoritative name server will be able to correct the typo and return the correct record to the user’s computer.
This is important because it prevents users from getting incorrect information or websites that are not authorized by the user’s domain name.
Authoritative name servers are also important because they can act as a middleman between the user’s computer and the DNS servers. If the user’s computer doesn’t have a direct connection to the DNS servers, then the authoritative name server can act as the user’s proxy and relay the requests to the DNS servers.
This is important because it allows users to access websites that are not normally accessible because the user’s computer isn’t configured to contact the DNS servers directly.
Overall, an authoritative name server is important because it ensures that the correct records are placed in the DNS database and that users can access websites that are not normally accessible.
