IPV4 stands for INTERNET Protocol version 4. It is the fundamental technology that makes it possible for us to connect our devices to the Internet. WHENEVER a device accesses the Internet it is assigned a unique, numerical IP address such as 128.255.244.221. To SEND data from one computer to another through the Internet, a data packet must be transferred across the NETWORK containing the IP addresses of both the sender and the receiver. Without IP addresses it is not possible for devices to communicate with each other. It is fundamental to the existence of the Internet.
