| IP (Internet Protocol) Addresses are the phone numbers of the internet.. |
| An IP address is a unique number that computers and devices connected to a network use to identify themselves (e.g. your home or office network, or the internet) An IP address can be thought of as the street address, or phone number of a particular device on the network. |
| An IP address can be shared by multiple devices using a "router". This is where showmemyipaddress.com comes in very handy. Windows (or whatever operating system you're using) may tell you your IP address is one number - but because of the router its not actually your real internet IP address. |
