How to Change DNS Server Settings in Mac OS X
Having appropriate DNS settings is essential for a Mac to be able to successfully access internet domains, whether it be a website like https://osxdaily.com or a remote server. DNS, which stands for Domain Name Server, essentially translates numerical IP addresses to the readable domains that most internet users are familiar with, and thus without properly functioning DNS servers you often will encounter DNS lookup errors, or slower than expected access.
While most internet server providers offer their own DNS servers, and most Macs will use DNS from DHCP or a wi-fi router, Mac users sometimes wish to change DNS settings themselves to custom servers, perhaps for better performance, or for troubleshooting purposes. This is easily accomplished in MacOS and Mac OS X as we’ll detail in this walkthrough.
