A namesserver is part of DNS that provides name-resolution services. It is one of the most important components of the Internet.
The DNS is a distributed system that uses name servers to share the burden of name resolution. This system is designed to handle large amounts of data quickly and efficiently.
In a name server distributed system, each nameserver has a list of IP addresses and host names for these names. These databases contain information that is configured with directives, resource records and zone files.
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.
These authoritative name servers have resource records that map IP addresses to host names. These are the main name servers in every zone.
They are sometimes called root servers or top level names servers. These servers are used as the core of the Internet’s domain name systems and maintained by many organizations worldwide.
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 results of all resolutions for names and returns them after a time period that is determined by retrieved zone records.
Dynamic update allows for entries to be added, deleted, or changed in zone files by using a command. Dynamic update is set up individually for each zone by adding a rule to allow update or update policy.
