What Is IP Addressing and How Is It Organized?

TL;DR

An IP address is a numerical label used to identify devices on a network, consisting of a network address and a host address. IP addresses are categorized into five classes (A, B, C, D, and E) based on their range and subnet masks, with Class A ranging from 1 to 127, Class B from 128 to 191, and Class C from 192 to 223.
