An IP address is an identification number assigned to a computer connected to an Internet network. Concretely, this number is used to identify machines and allow them to communicate with each other, by exchanging data on the Internet.

By default, operating systems have several internal tools to find out the IP address of the computer. In Windows, you have to open the command prompt and type the command ipconfig. Under Mac OS, open the Network panel located in System Preferences, and display the active connection. The IP address is presented as a series of numbers separated by periods, for example 192.168.1.30.
