How Do I Find My Secondary DNS Server?


Larry Thompson

When it comes to configuring your network settings, finding your secondary DNS server is an essential step. The secondary DNS server acts as a backup in case the primary server fails or becomes unavailable. In this tutorial, we will walk you through the process of finding your secondary DNS server.

Step 1: Open Network Settings

To begin, open the network settings on your device. The location of these settings may vary depending on the operating system you are using. Generally, you can find them in the Control Panel or System Preferences.

Step 2: Access Network Adapter Properties

Once you have opened the network settings, locate and select the network adapter that you are currently using. This could be Ethernet, Wi-Fi, or any other type of connection.

Note: If you are using a wireless connection, make sure you are connected to the network before proceeding.


If you are using Windows, right-click on the network adapter and select “Properties” from the context menu. This will open a new window with various properties related to your network connection.


If you are using a Mac, click on the gear icon labeled “Advanced.” This will open a drop-down menu with additional options for your network adapter.

Step 3: Locate DNS Server Settings

In both Windows and Mac, look for a tab or section labeled “DNS” or “TCP/IP.” This is where you can find and configure your DNS server settings.

Step 4: Identify Secondary DNS Server

In this section, you should see two fields for primary and secondary DNS servers. The primary server is usually filled in by default and is provided by your Internet Service Provider (ISP). The secondary server is typically left blank, but you can enter a secondary DNS server if you have one.

  • Note: If both primary and secondary DNS fields are already filled in, take note of the secondary DNS server as it is already configured.

Step 5: Finding a Secondary DNS Server

If you don’t have a secondary DNS server, you can find one by doing a quick search on the internet. There are several public DNS servers available that you can use as your secondary server. Some popular options include Google Public DNS (8.8.8) and OpenDNS (

To enter the IP address of the secondary DNS server, click on the field next to “Secondary DNS Server” and type in the IP address.

Step 6: Save and Apply Changes

After entering the IP address of the secondary DNS server, click on “Apply” or “OK” to save your changes.


In this tutorial, we have learned how to find and configure the secondary DNS server in your network settings. By having a secondary DNS server configured, you ensure that your network remains stable even if the primary server fails.

Note: It’s important to periodically check and update your primary and secondary DNS servers to ensure optimal network performance.
