Prefix hijacking

So let's imagine you have a special address that people use to send you letters. That address is like your own secret code and only you can use it. But imagine one day someone else decides to use your address too. They start getting all the letters that were meant for you! That's what prefix hijacking is like. It's when someone else starts using the special code (prefix) that is supposed to only be used by another person or organization. This can create big problems because people might try to send important information or messages to the wrong place, and it can make it hard for the real person or organization to get their messages. It's important for people to protect their special codes to prevent prefix hijacking.
