Domain server

« Back to Glossary Index


A Domain server is a server that acts as a central management point in a network. It stores information, manages user accounts, and provides access to certain network resources. The Domain server serves as a central hub for multiple devices that are on the network.

Domains are effectively the addresses of the Internet, and domain servers, often referred to as DNS (Domain Name System), translate these human-friendly addresses into IP addresses that can be read by computers.

For whom are domain servers useful?

  1. Website Owner:
    If you have or run your own website, you need a DNS server. Every time someone wants to visit your website, their computer asks the DNS server for the correct address. It's like asking for directions in a new city.
  2. Online Businesses:
    The more stable and faster your DNS, the better the user experience. Imagine you enter a store and the door opens immediately - that's what a fast DNS feels like.
  3. Large companies:
    Large companies with a global presence might even consider running their own DNS servers. It's like having a private VIP entrance just for you.
  4. Tech-savvy users:
    If you care a lot about privacy or just want more control over your Internet experience, you could use different DNS servers than the default option from your ISP. It's a bit like blazing your own trail through a forest instead of following the default path.

For whom domain servers may not be so important?

  1. Casual surfers:
    If you only occasionally surf the web, check email, or watch videos, you probably don't need to worry much about DNS. It's like a bicycle - if you only go for an occasional spin, you might not need the top-of-the-line model.
  2. Few tech-savvy:
    If you don't really want to dive deep into the technical aspects of the Internet, that's perfectly fine. Most internet providers set everything up so that it works without you having to worry about it.

In summary:
Think of the DNS system like the road system in a big city. Some people want to avoid the main roads, which are always congested, and prefer to take the side streets to get to their destination faster. Others, however, drive through the city only occasionally and simply take the shortest route. Still others may even want to build their own roads. No matter which group you belong to, it's important to know that you have options!

How does a domain server work?

The DNS is the phone book of the Internet, so to speak. It translates human-friendly domain names that we can easily remember and enter (like, into the IP addresses that computers use to communicate on the Internet.

Imagine you want to visit a website, let's say Here are the steps that your computer performs in the background:

  1. Request to the DNS resolver: Your computer, or more precisely your web browser, sends a request to a service on your device called the DNS resolver. This is usually provided by your Internet service provider.
  2. Request to the root server: The DNS resolver forwards the request to a root server. Root servers are effectively the first address books that are called to find out where the next piece of information can be found.
  3. Request to the TLD-Server: The root server responds to the resolver with the address of the top-level domain (TLD) Servers (in our example the TLD ".com"). The TLD-server manages all the information for the domains that point to this TLD end.
  4. Request to the authoritative server: The TLD-server then gives the resolver the address of the authoritative server for the specific domain ( The authoritative server has the concrete and authoritative answer to our question, which is the IP address for
  5. Response to the resolver: The authoritative server responds to the resolver with the IP address of the desired domain.
  6. Response to the web browser: Finally, the resolver passes the IP address to your web browser, which then connects to that IP address and loads the web page.

This may sound like a lot of effort for just one website call, but thanks to efficient Caching-methods and a huge distributed network architecture, the whole thing usually happens in a few milliseconds. And that's the magic of DNS: It allows us to simply remember names like "," while in the background a highly complex, finely tuned machinery ensures that we are connected to the right servers on the Internet.


A Domain server provides a central management point to manage multiple devices. This allows users to access a unified network and access resources such as files or printers. The Domain server can also serve as a security hub for the network by managing user authentication and authorization.


A Domain server may require a one-time investment to purchase and set up the server. However, once set up, there may be subsequent costs, such as storage costs, maintenance costs, energy costs, and service contract costs.

Use cases

The Domain server can be used in many areas, such as small businesses, educational institutions, and large organizations. It can be used as a means of managing user accounts, storing files, managing printers, and supporting network security.

Example 1

A company that wants to build a network can use a Domain server use. The server can be used to manage user accounts, store files and printers, and ensure the security of the network.

Example 2

A school network can also be operated by a Domain server benefit. The server can be used to manage accounts for students, teachers and staff, store files, manage printers and protect the network from attacks.


Domain servers, or more precisely DNS servers, are the invisible heroes of the Internet. Without them, surfing the net as we know it would be virtually impossible. They are the intermediaries between the human-friendly domain names and the machine-friendly IP addresses.

Imagine going into a huge library where there are no labels and no catalogs. The books are all there, but you have no idea where to find the book you're looking for. DNS servers are like the librarians who know exactly where each book is. Without them, we would get lost in the sea of information.

Moreover, DNS servers play a crucial role in ensuring security on the Internet. They can help protect users from threats such as phishing attacks by making sure that the domain you navigate to actually belongs to the organization it claims to represent.

Another example: Imagine you run an online store. Without DNS, your customers would not be able to reach your website unless they know the specific IP address of your server. But thanks to DNS, they can simply "" in their Browser and land directly on your page.

In short, without DNS servers, the Internet would be a pretty chaotic place. They are essential for making the vast amount of information on the Internet accessible and navigable. They are an integral part of the Internet and play a crucial role in almost everything we do online.
