Subnetting a Slash-26 Network

This animation breaks down a /26 subnet mask, showing how 26 network bits leave 6 host bits, giving 2^6 = 64 total addresses and 62 usable hosts after reserving the network and broadcast addresses. It also converts 192 into binary (11000000) to show how the mask maps onto the last octet. Useful for networking students learning CIDR notation, subnet masks, and binary-to-decimal conversion in IP addressing.
