Does everyone have the same IP address?

Never. There are IP addresses that are part of the internet world-wide, and are 100% unique. For example, the IP address that your ISP gives on your cable connection. If you connect your computer directly to your cable modem (NO ROUTER in between), then you will be assigned a public IP address.
