What DNS Server Does iOS Use?

The Domain Name System (DNS) is a crucial component of the internet infrastructure that translates human-friendly domain names, such as www.example.com, into IP addresses, which are required for computers to communicate with each other. When you connect to the internet using your iOS device, it relies on a DNS server to perform this translation.

Default DNS Server on iOS

iOS devices, including iPhones and iPads, typically use the DNS server provided by your internet service provider (ISP) by default. This means that when you enter a website address into your browser or any other network-related app on your iOS device, it sends a request to your ISP’s DNS server to resolve the domain name into an IP address.

Changing the DNS Server on iOS

If you wish to use a different DNS server on your iOS device for various reasons, such as improving speed or security, you have the option to change it. Here’s how:

  1. Open the “Settings” app on your iOS device.
  2. Select “Wi-Fi” from the list of options.
  3. Find and tap on the Wi-Fi network you are currently connected to (indicated by a checkmark).
  4. In the Wi-Fi settings page, scroll down and locate “DNS”. By default, it is set to “Automatic”.
  5. Tap on “DNS” and select “Manual”.
  6. You can now add one or more custom DNS servers by tapping on “Add Server”.
    • To add Google’s public DNS server (8.8.8), enter “8.8”.
    • To add Cloudflare’s public DNS server (1.1.1), enter “1.1”.
    • You can also add other DNS servers of your choice.
  7. Tap “Save” to apply the changes.

Note: Keep in mind that using custom DNS servers may have implications on network performance and access to certain websites or services, so it’s essential to choose reliable and trusted DNS providers.

Verifying DNS Changes on iOS

If you want to verify whether the DNS changes on your iOS device are working as intended, you can use various methods:

  • Browser: Open a web browser on your iOS device and visit a website like “https://www.whatismyip.com/”. It will display your IP address, which should correspond to the IP address associated with the DNS server you configured.
  • DNS Testing Tools: There are several online tools and mobile apps available that allow you to check the current DNS server being used by your iOS device.

In conclusion,

iOS devices rely on the default DNS server provided by your ISP for translating domain names into IP addresses. However, you have the option to change the DNS server in the Wi-Fi settings of your iOS device if desired. It’s recommended to choose reliable and trusted DNS providers for better performance and security.
