How to find my iPhone ip address

OK here goes........this won't really tell you anything useful.......but have at it.

Tap Settings on the Home Screen

Tap Wi-Fi

Tap on the blue circle "i" next to the name of the Wi-Fi network to which the phone is connected

Scroll down to find IP Address

Now that you have the local IP Address.......which will likely change in the next day or two.......what will you do with it?

Your phone’s IP address will change frequently and is assigned by the network you are connected to, either cellular or WiFi. Also, if you are connected to a private network, the IP address assigned to your phone will not be the same as the IP address that is seen by something you connect to on the Internet.

Why do you think you need to know what it is?
