A names server provides name resolution as part of the Domain Name System. It is an essential component of the Internet that determines the correct location for any host names on the network.
The DNS uses a distributed system of name servers that share the load of name resolution. This system has been designed to deal with large amounts data quickly.
Each name server in a distributed name server system has a database containing host names, IP addresses and other information. These databases are zone files. The information in them can be configured using directives and resources records.
When a user asks for the name of a particular host, a recursive server queries one or more authoritative name servers, which return a result to the recursive server and cache it closer to the client for future lookups. The recursive servers then return the result to the client, so that they can use it to perform further queries.
The authoritative name servers are the ones that contain the resource records which map host names to IP address. These are the primary name servers in each zone.
They are sometimes called root servers or top level names servers. These servers serve as a central point for the Internet's domain name system and are maintained by various organizations around the world.
There are four different types of name servers. These include master, slave and caching-only. Each type can be configured in different ways and performs different functions.
Masters keep the original authoritative zone records in a given namespace. These servers also respond to requests for the same namespace coming from other names servers.
Slaves receive zone information from their master. Zone transfer is the process that allows this to happen.
Caching-only acts as a second nameserver but does not have any authority over zones. It stores the results of all name resolutions and returns them to clients after a specified time period, which is determined by the retrieved zone record.
The dynamic update mechanism allows zone files to be changed or added with a single command. This option is configured separately for each entry in a zone file by adding a allow-update-or update-policy-rule.
