An IP adress is a combinaison of numbers like 192.168.1.1 or 18.104.22.168 (Google). Each IP adress has a location, an owner in order to get an internet connexion. It’s like an informatical ID.
IP means internet protocol address. It's like your home address, but on the internet!
Important note to make :
An IP address you see in your home network (e.g. 22.214.171.124) is a local address (just like you would have different mailboxes in a building). This is different from your public IP address which is the address that your router has when accessing different servers around the globe (just like the address of the buikding)
