Detailed explanation-1: -An IPv4 address is 32 bits. An IP Address is shown as 4 decimal numbers representing 4 bytes: d.d.d.d where d = decimal number (0-255). High order bits are the network identifier and lower order bits are the host identifier.
Detailed explanation-2: -IPv4 uses a 32-bit address space which provides 4, 294, 967, 296 (232) unique addresses, but large blocks are reserved for special networking purposes.
Detailed explanation-3: -IPv4 chose 32 bit because it was the biggest register found in any common processors at the time. It was an arbitrary choice that seemed good enough at the time. When IPv4 was originally devised we all believed it was sufficiently large enough. Few, if any, envisioned what happened 20+ years later.
Detailed explanation-4: -An IPv4 address is a 32 bits address, which is categorized into different IP classes.
