The domain name system (DNS) consists of a hierarchy of Nameservers, also known as DNS servers. The purpose of the DNS system is to translate human-readable domain names into IP addresses on a global scale.

Nameservers cache or host these translations.

In this article, we’ll delve into understanding what a nameserver is, its significance, and the mechanics behind its operation.

  • A nameserver is a crucial component of the DNS system, translating human-readable domain names into IP addresses that machines can understand
  • Nameservers support the resolution of domain names into IP addresses, enabling browsers to access websites by their domain names instead of IP addresses
  • Examples of nameservers include Google Public DNS (,, Cloudflare (,, and those provided by hosting services like Bluehost (ns1.bluehost.com, ns2.bluehost.com)

What Is a Nameserver for a Domain?

A nameserver is a dedicated server that plays a crucial role in the DNS hierarchy. The main goal of DNS is to translate human-friendly domain names, like “example.com”, into IP addresses, such as “”. And the main function of a nameserver is to store and manage these translations, or DNS records.

Every domain name has at least one or more nameservers assigned to it, and these nameservers hold the DNS records for that domain.

When you type a website address into your browser, it queries a nameserver to obtain the IP address of the website’s server. Once the IP address is retrieved, your browser can then connect directly to the server to fetch the website’s content.

Is a Nameserver the same as a DNS server?

DNS servers are often referred to as nameservers since DNS is the most common network service. However, there are alternative services including NetBIOS Name Service (NBNS), and IEN 116.

Nameservers vs DNS Records

Nameservers are special servers that manage and store DNS records for a specific domain. They are the primary source of information for that domain. When a DNS query is made, like when you type in a website address, nameservers provide the necessary DNS records that correspond to that domain.

DNS records are specific entries within the nameserver that provide details on various aspects of the domain.

These records indicate how different types of requests for the domain should be handled. They guide the internet traffic and dictate where emails should be delivered, which server a website is hosted on, and even help verify domain ownership.

Types of DNS Records: Some common DNS records include:

  • A Records: Point a domain or subdomain to an IP address.
  • MX Records: Direct where emails sent to the domain should be delivered.
  • CNAME Records: Alias one domain name to another.
  • TXT Records: Hold text information, often used for domain verification.
  • NS Records: Specify the authoritative nameservers for the domain.

Website Hosting vs Nameservers

Web hosting refers to the service that provides the physical storage space and resources for website files, data, and content.

This space is provided on servers that host websites and make them accessible to visitors from around the world. When you type in a web address and click on a link, you’re essentially requesting to view a website’s files. The hosting server then delivers those files to your browser, allowing you to view and interact with the website.

There are various types of hosting solutions such as shared hosting, dedicated hosting, cloud hosting, and more.

Nameservers, on the other hand, contain information on how domain names should be translated into IP addresses. Every domain has its own IP address, which is a numerical label that computers use to identify each other on a network.

When you enter a domain name into the browser bar, the browser consults nameservers to find the corresponding IP address.

Domain Name vs Nameservers

A domain name, like “example.com,” is a user-friendly address for a website, making web navigation intuitive without recalling complex IP addresses. It’s essentially the website’s online identity.

Domain’s nameservers, on the other hand, are the behind-the-scenes mechanisms directing where internet queries for a domain should go.

They contain DNS records, which match domain names to their corresponding IP addresses. When you enter a domain in your browser, nameservers guide the request, ensuring you reach the correct website.


In simple terms, if a domain name is a website’s name, nameservers are the directories that help you find it.

How Do DNS Nameservers Work?

Domain’s nameservers are the directories, like GPS devices that can help you navigate through a vast city to find the desired street address.

For example, when you type a website address like “example.com,” into your browser, nameservers provide the necessary information to translate the domain name into an IP address.

It can also process queries sent by the browser until the correct server’s IP address is found. Once it’s found, the nameserver responds to your browser with this address. Your browser then uses this IP address to load the website you requested.

How to Set Up Nameservers:

  • Choose a DNS Hosting Provider: Often, when you register a domain, your registrar (like GoDaddy or Namecheap) will offer DNS hosting, which includes nameservers. However, you can also opt for specialized DNS hosts for enhanced performance or security.
  • Update Domain Settings: After choosing a DNS host, they’ll provide nameserver addresses, typically looking like “host.examplehost.com.” Log into your domain registrar’s dashboard and replace the default nameserver addresses with those provided by your chosen DNS host.
  • Configure DNS Records: Within your DNS host’s dashboard, you’ll have the option to set various DNS records (like A, MX, or CNAME records). This configuration tells the nameserver how to respond to different queries about your domain, such as where your website or email is hosted.
  • Propagation: After updating settings, it can take anywhere from a few minutes to 48 hours for changes to propagate across the global network of nameservers. During this time, some users might be directed to your old site or server.

What Is the Purpose of a Nameserver?

The primary purpose of nameservers is to store and manage DNS records of translated user-friendly domain names, like “example.com”.

By doing so, they act as the internet’s directories, ensuring that when you type a website address, you’re directed to the correct server.

Setting them up is essential when configuring a new website or switching hosting providers; it ensures that your domain points to the right location.

Moreover, looking up nameservers can provide insights into where a domain is hosted or help in troubleshooting connectivity issues, ensuring a seamless online experience for users.

How to Find the Nameserver of Your Website

Finding the nameserver of your website is a straightforward process. If you’re considering changing it, it’s crucial first to identify the current one. Here’s how:

Via Your Domain Registrar:

  1.  Log in to the account where you registered your domain (e.g., GoDaddy, Namecheap).
  2. Navigate to your domain management or domain list section.
  3.  Click on the domain in question, and you should see details associated with it. The nameservers are usually listed in this section or in the DNS settings.

Online Lookup Tools:

  1. Visit a DNS lookup service like Whois.net, ICANN Lookup, or DNS Checker.
  2. Enter your domain name and perform the search.
  3.  The results typically display various details about the domain, including its nameservers.

How to Change Your Name Server for Different Domain Registrars

The process of changing your name server can vary across different hosting providers. Here’s a brief discussion of how it differs among the mentioned providers:
