IPv4 Address

    IPv4 addresses are 32 bits in size, which limits the address space to 4 294 967 296 (2³²) addresses. Of these, some addresses are reserved for special uses such as private networks (~18 million addresses) and multicast addresses (~270 million addresses).

    IPv4 addresses are usually represented in dot-decimal notation , which consists of four decimal places, each ranging from 0 to 255, separated by dots, e.g., 172.16.254.1 . Each part represents a group of 8 bits (one octet) of the address. IPv4 addresses can be presented in various hexadecimal, octal, or binary representations.
