Welcome back to Dev Odyssey Home Networking! In this episode, I cover what a subnet mask is, how a subnet mask works, and how subnetting works. I also talk about uses of subnets, writing subnet masks in Classless Inter Domain Routing or CIDR notation, and talk about basic subnet classes. We also see how subnet masks are written in binary, learn about the reserved IP addresses of a network, such as the Network ID and Broadcast ID, and learn how to calculate network, size and range using subnet masks.
