Your IP Address...
- Is a unique numerical address that is attached to every "packet" of information you send
- A "packet" is your message, your IP Address, and the IP Address of the computer receiving your message translated into binary
- Each packet of information can take a different route to its destination and can arrive at a different time from the other packets
