An IPv4 (Internet Protocol Version 4) network is a network that uses the fourth version of the Internet Protocol (IP) to identify and communicate with devices connected to the network. IPv4 is the most widely used protocol for connecting devices to the internet and is characterized by its use of 32-bit addresses that allow for the identification of up to 4.3 billion unique devices. IPv4 networks are commonly used for home and office networks, as well as for internet service providers (ISPs) and other large-scale networks. However, due to the limited number of available addresses in the IPv4 protocol, many networks are transitioning to the newer IPv6 (Internet Protocol Version 6) protocol which uses 128-bit addresses and can identify a much larger number of devices.
