If you want to track down someone’s IP address on an iPhone, there are a few different ways to go about it. One way is to open the Settings app on your iPhone and scroll down until you see the “General” section. Under “Network,” tap on “Wi-Fi.” Next, scroll down until you see the “IP Address” section. Tap on the “IP Address” button and type in the person’s IP address into the text field. Alternatively, you can open up a web browser on your iPhone and type in the person’s IP address into the URL bar. Once you’ve entered the URL, press Enter to open up the website. Finally, if you have access to someone’s iCloud account information, you can also use that to track down their IP address. ..
