We can send and receive data between two Pure Data applications in different computers provided that they are connected in a network. Before we can start the communication, we have to know the addresses of the two computers. The address that Pure Data uses is the IP address that we often come across the Internet. Once your computer is connected to the network, either through the wired Ethernet or the wireless Wi-Fi, we can obtain the IP address by the following methods.
In Mac OSX, we use the Network Utility inside the /Applications/Utilities folder. After we double-click on it to start the Network Utility, the front panel will show the IP Address of your computer.

In Linux, you also use the ifconfig command in the terminal window to display the IP Address as shown in the following screenshot:
In Windows...
