The difference between public and private IP addresses
When you use the internet, your messages and pictures first go through the network’s main code, called the public IP address. Then, like a postman delivering a letter to a specific apartment, the network uses the private IP address to give each message to the right device inside the network.
This switch from public to private codes is called “network address translation or NAT for short. It’s like making sure each letter reaches the right person in a big building.
