Changing your DNS servers on your Mac can speed up your Internet experience; this can speed up the translation of domain names to IP addresses. If you want to change your DNS server, we’ll show you how.
First, open System Preferences by clicking the Apple icon in the upper left corner of your Mac screen and selecting “System Preferences” from the menu that appears.
When System Preferences opens, click “Network”.
In Network preferences, use the sidebar to click the network adapter for which you want to configure DNS, such as “Ethernet” or “Wi-Fi”. Then click “Advanced”.
Under the advanced settings for the network adapter you selected, click on the “DNS” tab, then click on the plus (“+”) button just below the list labeled “DNS Servers”.
A text entry box will appear in the “DNS Servers” list. Type the DNS address you want to use, then press Return.
For example, to use Google DNS, add these four addresses to the list using the plus button. The first two are IPv4 addresses and the second two are IPv6 addresses:
You can also use other alternative DNS services such as OpenDNS or any other DNS server of your choice.
After that, click “OK” to close the advanced network settings window.
Back on the main network preferences page, if you also want to configure the DNS servers for another network adapter (like “Ethernet” if you plan to use it as well as Wi-Fi), click on it and repeat the steps. above. When you’re done, click “Apply” in the lower right corner of the Network Preferences window.
From now on, your Mac uses new alternate DNS servers. Good navigation !
