Safari browser doesn't have it's own DNS settings. Instead, it relies on the system-wide DNS settings. There are 3 options, choose the one the suits you best:
- Set up Smart DNS on macOS (MacBook, iMac)
- Set up Smart DNS on iOS (iPhone, iPad)
- Set up Smart DNS on your router
Enabling Smart DNS on the Wi-Fi router will force it on all the devices connected to that Wi-Fi network. Enabling it on macOS or iOS will force it for all apps on respective device (including Safari).
Don't worry - using our Smart DNS doesn't affect your internet connection in any negative way.
