How to Change DNS Settings on iPhone & iPad: A Step-by-Step Guide

When you navigate to a website on your iPhone or iPad, your device performs a DNS lookup to ensure you’re directed to the correct location. Most devices default to the DNS servers provided by your internet service provider (ISP), but sometimes these servers can be slow or cause network issues. In this guide, we’ll walk you through the process of changing your DNS settings on iOS, helping you improve your internet speed and troubleshoot network problems.

Please note that you will need to be connected to a Wi-Fi network to change DNS settings. For iPhones, the DNS is set by your mobile carrier and cannot be modified until you connect to a Wi-Fi network.

Changing DNS Settings in iOS

Changing DNS settings is a straightforward process on all iOS devices, regardless of the version of the operating system. Here’s how you can do it:

  1. Open the Settings app on your iPhone or iPad and tap on Wi-Fi.
  2. Locate the Wi-Fi network you’re connected to, and tap on the (i) button next to its name.
  3. Changing DNS servers on iPhone and iPad

  5. Configure DNS servers on iPhone

  6. Tap the “Back” button or exit Settings to save the DNS changes.

That’s it! You have successfully changed the DNS settings on your iOS device. However, please note that the changes may not take effect immediately.

Enforcing DNS Changes

To ensure that the DNS changes take effect, it is recommended to restart your iPhone, iPad, or iPod touch. This will clear any cached DNS information. You can either restart the device by holding down the power button and turning it off and on again, or use the software restart method if the physical buttons are not available.

How to Determine Which DNS Servers You’re Using

By default, Wi-Fi routers automatically assign a DNS server via DHCP, usually obtaining the information from your ISP. Generally, you will see something like “” in the DNS settings. Unless you are experiencing specific issues or looking to improve performance, there’s usually no need to change them. However, if you prefer to use different DNS servers, you can consider using the following public DNS services:

Google Public DNS IP addresses:

OpenDNS IP addresses:


If you are unsure which DNS servers to use, you can test the performance of different DNS services using an app like NameBench. Running this test on a Mac or Windows PC can help you determine the fastest DNS server for your network and location, resulting in an improved internet experience and better performance.
