Introduction to IPv4

IPv4, which stands for Internet Protocol version 4, is the fourth version of the Internet Protocol (IP) that was originally designed in the early 1980s and has been widely used since the early days of the internet.

IPv4 is the underlying technology that allows devices to communicate with each other over the internet and other IP-based networks.




IP v4 addresses are made up of bits.

The maximum number of IPv4 addresses that can be assigned is 4.3 .

An IPv4 address is divided into and host portions.

An organization can obtain a block of IP addresses from an Internet Service Provider (ISP).

The use of IP addresses helps conserve IPv4 address space.

When a device communicates with the internet, its private IP address is translated to a IP address through a process called Network Address Translation (NAT).
