How to change DNS server on your iPhone

The DNS (Domain Name System) allows the domain name to be translated into the corresponding IP address to which it corresponds. Every time we connect to a site by writing its name in the search bar, this translation process takes place. One reason for wanting to change your address on the iPhone is to speed up the Internet. In this simple guide we will explain how to change it on your iPhone.

How to change DNS on the iPhone

To verify that everything is working properly, it will be enough to carry out a test by entering the domain name of a website in the search bar (eg


If we want to return to the previous settings, just enter the old addresses again and insert the previous ones. If we do not remember them we will just have to dissociate ourselves from the network to which we are connected, selecting Dissociate this network, and connect again.
