That led to the introduction of IPV6 – a 128-bit address capable of supporting more devices. However, the growth of the internet, e.g., IoT (Internet of Devices), has led to the depletion of IPV4 addresses. There are two main IP address versions: the IPV4 (IP address Version 4) and IPV6 (IP address Version 6). An IP address (Internet Protocol address) is a numerical number assigned to every device connected to a network communicating using the Internet Protocol.
