IPv4

IPv4 stands for Internet Protocol version 4. It is a protocol used to identify devices on a network and route Internet Protocol (IP) packets between them.
IPv4 uses 32-bit addresses, which are expressed in four groups of numbers separated by dots, for example, 192.168.0.1. Each group represents 8 bits, allowing for a total of 2^32 or approximately 4.3 billion unique IP addresses.
