DNS (Domain Name System) is a crucial component of any network infrastructure, including Apple environments. It plays a vital role in translating human-readable domain names into IP addresses, enabling communication between devices over the internet. In the Apple environment, DNS is essential for various tasks, such as accessing websites, sending emails, and connecting to network resources.

One adjustment in the Apple environment is the integration of DNS with the macOS operating system. macOS includes a built-in DNS resolver that interacts with DNS servers to resolve domain names. This integration ensures seamless DNS functionality across Apple devices, including Macs, iPhones, and iPads.

Examples:
1. Configuring DNS on macOS:

• Open System Preferences on your Mac.


• Click on "Network" and select your active network connection.


• Click on "Advanced" and navigate to the "DNS" tab.


• Here, you can add, remove, or modify DNS server addresses.


• Click "OK" to save the changes.

2. Troubleshooting DNS issues on iOS:

• Open the "Settings" app on your iPhone or iPad.


• Tap on "Wi-Fi" and select your connected network.


• Tap on the "i" icon next to the network name.


• Scroll down and tap on "Configure DNS."


• Select "Manual" and tap on "Add Server" to enter custom DNS addresses.


• Tap "Save" to apply the changes.
