Episode 17: IPv4 Addressing — Structure and Notation
IPv4 addressing is one of the most tested topics on the Network Plus exam, and this episode gives it the detailed attention it deserves. We start with the structure of an IPv4 address and explain dotted decimal notation, subnet masks, and how addresses are broken into network and host portions. You’ll learn about binary conversion, address classes, and the use of CIDR.
We also cover private vs. public ranges, loopback addresses, and reserved spaces for special purposes. This episode lays the foundation for understanding IP networking, routing, and subnetting in future episodes.
