The WAN (=Wide Area Network) IP address is the external IP address your router is connected to the internet with. It gets assigned by your internet service provider (ISP) and typically changes every time when your router (re-)connects to the internet. There are a couple of way to get your current IP address when you are connected to a device in your network.
