Public IP Address and Private IPIP address (Internet Protocol) is a numerical identification to detect your computer in a network. It is used to communicate between nodes in a computer network. When you connect to the Internet through an ADSL modem, it has two network interfaces:

A private interface, used to network computers connected to the router; their IP address is typically in the range 192.168.0.* or 192.168.1.*, the router will connect to the gateway with an IP address in the range of 192.168.0.1 or 192.168.1.1. A command via the computer will allow you to determine the private IP address that has been assigned to your router.

Otherwise, simply log onto specialized sites to access this particular information.
