of an IP address can be regarded as an 8-bit unsigned integer, that is, 0-255. Each segment is split into a binary array and then converted into a binary number. An unsigned 32 is an integer. For example, an IP address is 10.0.3.193. The binary number corresponding to each digit. 10 00001010 0 00000000 3 00000011 193 11000001 In combination, the IP address is 00001010 00000000 00000011 11000001, and the value is 167773121, that is, the number after the IP address is converted.
