Find the IPv4 address of your raspberry device (ignore this step, if you already know the IP of your device)
command: ifconfig -a | grep 192.168
=> You can also verify the IPv4 assigned from your router by comparing the mac address
Connect to your raspberry device
command: ssh pi@192.168.1.109
=> If your device and your phone is connected on same network you can access it.
=> If you want to connect to the actual IP assigned by your ISP (usually for remote access), you must enable forwarding on your router and link your raspbebrry device.
