What is IP?
What does it mean?
IP - Internet Protocol - It is what identifies every electronic device connected to the internet.
What does it do?
It allows us to get information from one IP from another, it is like being connected through a phone line.
Why do we need it?
We have it because if we didn't then all devices would be scattered around not named, so something called IPv4 was created so that all devices would be identified so they can connect with who ever they like.
