What are Nameservers and how do they Work?

When it comes to setting up your blog or website, there are a few key terms and concepts that you should familiarize yourself with. One of these is nameservers, which play a crucial role in ensuring that your website is accessible to visitors.

What are Nameservers?

Nameservers can be thought of as the internet’s phone book. They are specialized servers that translate human-readable domain names, such as, into machine-readable IP addresses, like These IP addresses are used by computers to identify and communicate with each other on a network.

When you enter a domain name in a web browser, the nameservers come into action. They direct you to the correct web hosting server where the website associated with that domain name is stored. In other words, nameservers ensure that when someone types in your domain, they are directed to the right web hosting server to access your website or services.

How Do Nameservers Work?

When you register a domain name, you typically do so through a domain registrar. During the registration process, you are asked to provide the nameservers for your domain. These nameservers are usually provided by your web hosting provider.

Once you have set up your nameservers, they are responsible for handling all the domain name resolution requests for your website. When a visitor enters your domain name in their web browser, the browser sends a request to the nameservers associated with your domain.

The nameservers then look up the IP address associated with your domain and provide it to the visitor’s browser. The browser can then connect to the web hosting server using the provided IP address and retrieve the website’s content.

Changing Nameservers

If you decide to change your web hosting provider or transfer your domain to a different registrar, you may need to update your nameservers. This process is typically done through your domain registrar’s control panel.

When changing nameservers, it’s important to ensure that the new nameservers are properly configured and ready to handle your domain’s requests. This may involve updating DNS records and allowing for propagation time, during which the changes are propagated across the internet.

Nameservers and DNS

Nameservers are an essential component of the Domain Name System (DNS). DNS is a distributed database that stores information about domain names and their corresponding IP addresses. When a request is made to resolve a domain name, the nameservers consult the DNS to provide the necessary information.

There are different types of nameservers within the DNS hierarchy, including authoritative nameservers and recursive nameservers. Authoritative nameservers are responsible for storing and providing the DNS records for a specific domain, while recursive nameservers help resolve domain names by querying authoritative nameservers.


Nameservers are an integral part of the process that allows users to access websites and services on the internet. They act as the bridge between human-readable domain names and machine-readable IP addresses, ensuring that visitors are directed to the correct web hosting server for a particular domain. Understanding how nameservers work and how to manage them is essential for anyone setting up a blog or website.

Frequently Asked Questions


Here are 10 frequently asked questions about nameservers

1. **What is a nameserver?**

– A nameserver is a specialized server on the internet that manages the mapping between domain names and IP addresses. When a user enters a domain name into their web browser, the nameserver translates that domain name into the corresponding IP address, allowing the browser to connect to the correct web server where the website is hosted.

2. **How do nameservers work?**

– Nameservers work by storing DNS (Domain Name System) records that map domain names to IP addresses. When a user requests a website by entering a domain name into their web browser, their computer sends a DNS query to a nameserver. The nameserver then looks up the corresponding IP address in its DNS records and returns it to the user’s computer, allowing the browser to connect to the correct web server.

3. **What is the difference between authoritative and recursive nameservers?**

– Authoritative nameservers are responsible for storing and providing DNS records for specific domains. When a user’s computer queries an authoritative nameserver for a domain’s DNS records, the nameserver returns the authoritative information for that domain. Recursive nameservers, on the other hand, are responsible for resolving DNS queries by recursively querying other nameservers until they find the authoritative nameserver for the requested domain.

4. **How do I find out what nameservers are currently assigned to my domain?**

– You can find out what nameservers are currently assigned to your domain by performing a WHOIS lookup on your domain name. WHOIS lookup tools provide information about domain registration details, including the nameservers assigned to the domain. Additionally, many domain registrars provide management interfaces where you can view and modify your domain’s nameserver settings.

5. **Can I change my domain’s nameservers?**

– Yes, you can change your domain’s nameservers through your domain registrar’s management interface. Typically, this involves logging into your registrar account, accessing your domain settings, and entering the new nameserver information provided by your web hosting provider or DNS service provider. Keep in mind that changes to nameservers may take some time to propagate across the internet.

6. **How long does it take for nameserver changes to take effect?**

– Nameserver changes typically take anywhere from a few minutes to 48 hours to propagate across the internet. During this propagation period, DNS records are updated and cached by ISPs (Internet Service Providers) and DNS resolvers around the world. The exact time it takes for changes to take effect depends on various factors, including TTL (Time to Live) settings and DNS caching policies.

7. **What is a nameserver delegation?**

– Nameserver delegation is the process of assigning authority for managing a domain’s DNS records to specific nameservers. This is done by updating the domain’s nameserver settings to point to the authoritative nameservers responsible for hosting the domain’s DNS records. Nameserver delegation allows domain owners to control how their domain’s DNS information is managed and accessed.

8. **What are DNS zone files, and how are they related to nameservers?**

– DNS zone files are text files that contain DNS records for a specific domain. These records include information such as IP addresses, MX (Mail Exchange) records, and other DNS settings. Nameservers use DNS zone files to store and serve DNS records for the domains they are authoritative for. When a DNS query is made for a domain, the nameserver references its zone file to retrieve the corresponding DNS records.

9. **What is DNS propagation, and how does it affect nameserver changes?**

– DNS propagation refers to the time it takes for DNS changes, such as nameserver updates or DNS record modifications, to be distributed and recognized across the internet. During DNS propagation, updated DNS information is cached and propagated by DNS servers worldwide. Nameserver changes may not be immediately visible to all users until DNS propagation is complete, which can take anywhere from a few minutes to 48 hours.

10. **Can I host my own nameservers?**

– Yes, it is possible to host your own nameservers if you have the technical expertise and resources to do so. Hosting your own nameservers allows you to have complete control over your DNS infrastructure and can be advantageous in terms of performance, security, and customization. However, hosting your own nameservers also comes with responsibilities for maintaining and securing the servers, ensuring uptime, and managing DNS configurations effectively.
