DNS is an essential part of the internet. It is responsible for translating domain names into IP addresses, which are the numerical addresses that computers use to communicate with each other. Without DNS, you would not be able to access websites by typing in their domain names.
There are many different ways to check your DNS settings on a Mac. The easiest way is to use the Network Utility app. To do this, open the Applications folder and then open the Utilities folder. Double-click on the Network Utility app.
1. Open System Preferences
To check the DNS settings on a Mac, you must first open the System Preferences menu. This menu is the central hub for managing all of the settings on your Mac, including network settings. Once you have opened the System Preferences menu, you can click on the “Network” icon to access the network settings. From there, you can click on the “Advanced” button to view the DNS settings.
The System Preferences menu is an important part of macOS because it allows you to customize your Mac to your liking. You can use the System Preferences menu to change the appearance of your Mac, add or remove users, and configure your network settings. The System Preferences menu is also where you can go to troubleshoot problems with your Mac.
If you are having trouble connecting to the internet, you can check your DNS settings to see if they are correct. Incorrect DNS settings can prevent your Mac from resolving domain names to IP addresses, which can make it impossible to access websites. By following the steps outlined above, you can check your DNS settings and make sure that they are correct.
2. Locate Network
To check the DNS settings on a Mac, you must first locate the “Network” icon in the System Preferences menu. This icon provides access to all of the network-related settings and configurations on your Mac, including the DNS settings. Once you have located the “Network” icon, you can click on it to open the Network pane.
- Network Interface Selection: The Network pane displays a list of all the network interfaces on your Mac. You can select the network interface that you want to configure from this list. Once you have selected the network interface, you can click on the “Advanced” button to view the DNS settings.
- DNS Server Configuration: The DNS settings are located in the “DNS” tab of the Advanced pane. In this tab, you can view and modify the DNS servers that are used by your Mac. You can also add or remove DNS servers from this tab.
- DNS Troubleshooting: If you are having trouble connecting to the internet, you can troubleshoot the DNS settings by using the “Diagnostics” button in the DNS tab. The Diagnostics button will run a series of tests to check the DNS settings and identify any problems.
- Advanced DNS Settings: In addition to the basic DNS settings, there are also a number of advanced DNS settings that you can configure. These settings are located in the “Advanced” tab of the Network pane.

3. Advanced Options
The “Advanced” button in the Network pane provides access to a range of advanced network settings, including the DNS settings. These settings allow you to configure your Mac’s network connection in more detail, giving you greater control over how your Mac connects to the internet.
The DNS settings are particularly important because they determine how your Mac resolves domain names to IP addresses. Domain names are the human-readable names of websites, such as “www.apple.com”. IP addresses are the numerical addresses of websites, such as “17.178.96.59”. When you type a domain name into your web browser, your Mac uses the DNS settings to resolve the domain name to an IP address. This allows your Mac to connect to the website.
If the DNS settings are incorrect, your Mac may not be able to resolve domain names to IP addresses. This can prevent you from accessing websites or using other internet services. By clicking on the “Advanced” button and configuring the DNS settings, you can ensure that your Mac is able to connect to the internet properly.
In addition to the DNS settings, the “Advanced” pane also provides access to other advanced network settings, such as the proxy settings, the TCP/IP settings, and the firewall settings. These settings allow you to fine-tune your Mac’s network connection and optimize its performance.
Understanding how to use the “Advanced” options in the Network pane is essential for troubleshooting network problems and optimizing the performance of your Mac.
4. DNS Tab
The “DNS” tab in the Network pane provides access to the DNS settings for your Mac. These settings determine how your Mac resolves domain names to IP addresses, which is essential for connecting to websites and other internet services.
- DNS Server Selection: The “DNS Servers” field in the “DNS” tab displays a list of the DNS servers that are currently being used by your Mac. You can add or remove DNS servers from this list by clicking on the “+” or “-” buttons.
- Custom DNS Servers: If you want to use custom DNS servers, you can enter their IP addresses into the “DNS Servers” field. Custom DNS servers can be used to improve your privacy, security, and performance.
- DNS Cache: The “DNS Cache” section of the “DNS” tab displays a list of the DNS entries that are currently cached by your Mac. The DNS cache stores the IP addresses of recently resolved domain names, which can speed up your browsing experience.
- DNS Diagnostics: The “Diagnostics” button in the “DNS” tab can be used to troubleshoot DNS problems. The Diagnostics button will run a series of tests to check the DNS settings and identify any problems.
Understanding how to use the “DNS” tab is essential for troubleshooting network problems and optimizing the performance of your Mac.
