How to Add a Custom DNS Server on iPhone

Previously, we shared a guide on how to add a custom DNS server on Android. Now, let’s look at how to do the same on an iPhone. Just like Android, you can easily set up custom DNS servers on your iPhone without needing to install any additional apps. The process is straightforward.

Before diving into the steps, let’s briefly cover what DNS is and its role.

What is DNS?

DNS, or Domain Name System, is an automated process that matches domain names to their corresponding IP addresses. Whenever you enter a website URL in your browser, DNS servers work to identify the IP address associated with that domain. Once matched, the DNS server communicates with the website’s server, allowing the web page to load.

In most cases, this process is automatic and seamless. However, sometimes DNS servers fail to match the IP address, causing errors like “DNS probe started,” “DNS lookup failed,” or “DNS server not responding.”
