Can a hacker steal my ip?

IP addresses only exist in software.

There is no single IP address linked to you or your device.

Your ip address changes when you connect to different networks.

IP addresses are broadcast along with any web traffic, it’s how the network routes your requested data to you.

here is a diagram of what an IP packet looks like:

"Can a hacker steal my ip?: Also how would I know if my phone is cloned . I really think someone is listening in on my phone calls."

Hacked IP Address:

If you have a Static IP Address (on assigned to your on a network), then one might find it in a data base or a list of sorts.

Factory Restoring iPhone:

If you are so concerned, then you should factory reset your iPhone - Apple Support, backing up first. IMPORTANT: be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the reset.

Your iPhone cannot be cloned. No one is listening in on your calls. Because your iPhone is not susceptible to hackers.

It’s not. They aren’t.
