IP address classes were the early internet’s way of carving the address space into neat, rigid blocks. In this episode, we break down how classful addressing worked, how the prefix–suffix structure separated networks from hosts, and why the internet eventually outgrew this system. Each class—A, B, C, D, and E—was designed for a different scale or purpose, from massive global networks to tiny LANs, multicast groups, and experimental ranges. Understanding these legacy classes gives context for how subnetting and CIDR evolved to replace the old, wasteful structure.🌐 Reserve your permanent digital ad space: AdParcel.io📗 Learn software testing in 1 day: TestingIn1Day.com💻 Connect with tech founders: StartupMafia.net
