IP and numbers are converted to each other, and the converted number is a 32-bit unsigned integer number. IPv4 address is a 32-bit binary number, which is usually divided into 4 "8-bit binary numbers" (that is, 4 bytes). IP addresses are usually expressed in the form of (a.b.c.d) by "dotted decimal", where a, B, C and D are decimal integers between 0 and 255. For example, the dotted decimal IP address (100.4.5.6) is actually a 32-bit binary number (01100100.00000100.00000101.00000110).
