FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The IP protocol identifies each computer connected to the network by its corresponding address. This address is a 32 bits number in Ipv4, that has to be unique for each server or computer, which we will call “host”. The IP addresses are usually represented as four decimal ciphers, of 8 bits each, separated by dots.

Detailed explanation-2: -The IPv4 address is a 32-bit number that uniquely identifies a network interface on a machine. An IPv4 address is typically written in decimal digits, formatted as four 8-bit fields that are separated by periods. Each 8-bit field represents a byte of the IPv4 address.

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: -The IPv4 is a 32-bit address, whereas IPv6 is a 128-bit hexadecimal address. IPv6 provides a large address space, and it contains a simple header as compared to IPv4. IPv6 increases the IP address from 32 bits to 128 bits to support larger address demands.

Detailed explanation-5: -If an IPv4 address is made up of four sections with 256 possibilities in each section, to find the total number of IPv4 addresses, you should just multiply 256 256 256 * 256 to find results 4, 294, 967, 296 addresses. To put it another way, we have 32 bits then 2 to the 32nd power will give the same result obtained.
