Your home and mobile internet IP address is a unique address that identifies a device on your internet or a local network. For mobile devices, your IP address will change as you travel because mobile networks will jump from cell tower to cell tower to keep your service running seamlessly. This is why security login emails and ‘my location‘ info tends to be off on mobile devices.
To find your IP address for both mobile and home devices type “what’s my IP address” in your web browser.
