This video provides an overview of Class A, Class B, and Class C address structure and its hierarchical nature. Understanding host to tell the difference between the different classes by IP address is mandatory. He also explains how to look at the first bits in the first byte of each address to determine the address class.

- [Instructor] One of the most important topics…in any discussion of TCPIP is IP addressing.…An IP address is a numeric identifier…assigned to each machine on an IP network.…It designates the specific location…of a device on the network.…An IP address is a software or logical address,…not a hardware address like our Mac addresses.…IP addressing was designed to allow hosts on one network…to communicate with hosts on a different network,…regardless of the type of LAN…the hosts are participating in.…
Shown in the graphic, an IP address…is comprised of 32 bits of information.…These bits are divided into four bytes,…or four sections.…They're referred to as octets or bytes,…each containing eight bits.…The 32 bit IP address is structured, or hierarchical,…as opposed to a flat or non-hierarchical address.…Although either type of addressing scheme…could've been used, hierarchical addressing…was chosen for a good reason.…The advantage of the scheme is that it can handle…a large number of addresses, namely 4.3 billion.…
The network address, which is defined…
