IPv4

IPv4, or Internet Protocol Version 4, is the fourth version of IP (Internet Protocol). It's a foundational protocol that routes most of the Internet traffic today, even with the growing reach of IPv6. IPv4 is responsible for identifying devices on a network through an addressing system. The IPv4 uses a 32-bit address schema allowing for a total of just over 4 billion addresses. Most importantly, IPv4 determines how data is sent and received over network devices. This standard of IPv4 helps to route data between networks and has been foundational in the creation of the modern Internet.
