If you’re like most people, you probably have a default IP address set up on your iPhone. This is your device’s public IP address, which is used by Apple to connect to the internet. If you want to change this IP address, you can do so by going to the Settings app and selecting “IP Address.” There, you’ll find a list of all of your devices in order from the bottom. You’ll need to select your iPhone in the top row and then click on the “Change” button. Once you’ve changed your IP address, it will be applied automatically and will be visible in all of your devices’ settings.
