Understanding IPv4 Subnetting (Part 2)

This article clarifies IPv4 subnetting by explaining how subnet masks and CIDR notation determine network versus host bits, how binary AND yields network addresses, and how to convert between binary and decimal masks (e.g., /22 = 255.255.252.0). It provides practical examples like splitting 192.168.1.0 into four /26 subnets with their network, broadcast, and usable ranges, highlights reasons to subnet (segmentation, limiting broadcasts, organizational clarity), and notes reserved network/broadcast addresses.
