How Do I Find My DNS Server on CentOS?


Scott Campbell

Are you looking to find your DNS server on CentOS? Look no further! In this tutorial, I will guide you through the process of finding your DNS server using simple commands in CentOS.

Why do I need to find my DNS server?

Before we dive into the steps, let’s quickly understand why it is important to know your DNS server. The Domain Name System (DNS) is responsible for translating domain names into IP addresses. It acts as a phonebook of the internet, enabling you to access websites by simply typing their domain names instead of remembering complex IP addresses.

In certain cases, such as troubleshooting network issues or configuring network settings, you may need to know which DNS server your CentOS system is using. So, let’s get started!

Finding Your DNS Server on CentOS

To find your DNS server on CentOS, follow these simple steps:

Step 1: Open Terminal

The first step is to open the terminal on your CentOS system. You can do this by navigating to the Applications menu and selecting Terminal or by using the shortcut Ctrl+Alt+T.

Step 2: Use the ‘cat’ Command

Once you have the terminal open, type the following command and press Enter:

cat /etc/resolv.conf

This command will display the contents of the /etc/resolv.conf file.

Step 3: Look for ‘nameserver’

In the output of the previous command, look for a line starting with nameserver. This line indicates the IP address of your DNS server.

nameserver 8.8.8

In this example, the DNS server is 8.8. It might be different for your system.

Step 4: Note down the DNS server

Note down the IP address mentioned after nameserver. This is your DNS server’s IP address.


Finding your DNS server on CentOS is a simple process that can be accomplished using the terminal and a few commands. By knowing your DNS server, you can troubleshoot network issues and configure network settings effectively. Remember to note down the IP address of your DNS server for future reference.

I hope this tutorial has helped you find your DNS server on CentOS! If you have any further questions or need more assistance, feel free to reach out.
