Does DNS Server Need Internet?

When it comes to understanding how the Domain Name System (DNS) works, one common question that often arises is whether a DNS server needs internet access. In this article, we will delve deeper into this topic and explore the role of the internet in the functioning of a DNS server.

What is a DNS Server?

Before we answer the main question, let’s start by understanding what a DNS server is. In simple terms, a DNS server is responsible for translating human-readable domain names (such as into IP addresses that computers understand.

A DNS server acts as a directory that helps route internet traffic efficiently. When you type a domain name into your web browser, your computer contacts a DNS server to obtain the corresponding IP address. This allows your computer to establish a connection with the correct website or online service.

Primary and Secondary DNS Servers

In most cases, organizations use two types of DNS servers – primary and secondary. The primary DNS server stores all the information about domain names and their corresponding IP addresses. The secondary DNS server acts as a backup in case the primary server experiences any issues or becomes unavailable.

The Role of Internet in DNS Resolution

To answer our main question – yes, a DNS server does require internet access to fulfill its purpose effectively. Here’s why:

  • DNS Query: When you enter a domain name in your web browser, your computer sends out a query to the configured DNS server over the internet. This query contains the domain name that needs to be resolved into an IP address.
  • DNS Root Servers: The configured DNS server then sends your query to one of several authoritative DNS root servers.

    These root servers hold information about top-level domains (TLDs) such as .com, .org, .net, etc.

  • Top-Level Domain Servers: The authoritative DNS root server responds to your query with the IP address of the top-level domain server responsible for the specific TLD in your domain name.
  • Name Server Hierarchy: Your DNS query then moves down the hierarchy until it reaches the name server responsible for the specific domain you entered. This name server holds information about the IP address associated with that domain.
  • DNS Response: Finally, the IP address associated with your domain name is sent back to your computer over the internet. Your web browser can now establish a connection to the desired website or online service.


In conclusion, a DNS server indeed requires internet access to perform its crucial role in translating domain names into IP addresses. Without an internet connection, a DNS server cannot effectively resolve queries and provide accurate responses. Understanding how a DNS server functions and its dependency on the internet is essential for maintaining a reliable and efficient network infrastructure.
