Article Introduction：An ipv4 address consists of 32-bit binary numbers. IPv4 is the 4th version of the Internet communication protocol. IPv4 uses 4 bytes. Each section contains 8 address bits. A total of 32 binary digits represent the network address. According to the number of binary digits of ipv4, it can be seen that ipv4 can represent a total of networks. The address is 2 raised to the 32nd power, which is equal to 4294967296, which is approximately 4.3 billion.
