What Is Name Server in DNS?


Heather Bennett

When it comes to the Domain Name System (DNS), one term that you may often come across is “Name Server.” But what exactly is a Name Server in DNS? In this article, we will dive deep into the concept of Name Servers and understand their importance in the functioning of the DNS.

Understanding Name Servers

In simple terms, a Name Server is a computer server that is responsible for translating domain names into IP addresses. It acts as a directory service that allows users to access websites using human-readable domain names, rather than remembering complex IP addresses.

When you type a domain name in your web browser’s address bar, your computer sends a request to a Name Server to find out the IP address associated with that domain name. The Name Server then responds with the corresponding IP address, allowing your computer to establish a connection with the desired website.

Types of Name Servers

There are several types of Name Servers that play different roles in the DNS infrastructure. Let’s take a look at some of the commonly used ones:

  • Root Name Servers: These servers are at the top of the DNS hierarchy and store information about all top-level domains (TLDs). They are managed by various organizations and play a crucial role in resolving domain names.
  • TLD Name Servers: These servers handle requests for specific top-level domains such as .com, .org, .net, etc.

    They maintain information about all domains within their respective TLDs.

  • Authoritative Name Servers: These servers are responsible for storing and providing authoritative information about specific domain names. Each domain typically has multiple authoritative name servers for redundancy and load distribution.
  • Recursive Resolvers: These servers act as intermediaries between client devices and the DNS infrastructure. They receive DNS queries from client devices, and if they don’t have the necessary information, they recursively fetch it from other Name Servers.

Name Server Configuration

To ensure proper functioning of a domain’s Name Servers, their configuration is crucial. The domain owner must specify the correct Name Server addresses provided by their hosting provider or DNS service. This ensures that the domain’s DNS records are properly managed and can be resolved correctly.

It is important to note that changes made to the Name Server configuration may take some time to propagate across the DNS network. This propagation period can range from a few minutes to several hours, during which some users may still be directed to the old Name Servers.


In conclusion, Name Servers are an integral part of the Domain Name System (DNS) infrastructure. They facilitate the translation of domain names into IP addresses, allowing users to access websites easily. Understanding how Name Servers work and their different types can help you troubleshoot DNS-related issues and ensure smooth functioning of your website.

So next time you type a domain name in your browser, remember that behind the scenes, Name Servers are working tirelessly to make sure you reach your desired destination on the web!
