Packets have something on them called packet headers which contains information like what protocols are being used, where the destination is, where the source is etc. This is how routers in a network know where to send and how to handle information being transmitted across them. Think of it like a mail man with a bag full of mail. How do the letters not get mixed up? Each one is in its own envelope which on it has all the information to ensure it gets where its going or gets returned if the destination doesn’t exist.
