🎯 What you'll learn: IPv4 address structure and binary representation, subnet masks and the AND operation, network/host/broadcast addresses, unicast vs broadcast vs multicast, public and private address ranges, basic subnetting, VLSM (Variable Length Subnet Masking), and a subnet mask quick-reference guide.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1/24 means how many network bits?
2Hosts in a /24:
3The all-ones host portion is the:
4192.168.10.0/26 subnets a /24 into:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5255.255.255.0 equals prefix /.
6Usable hosts = 2^host-bits minus .
7Subnet 192.168.1.0/24 into 4 - list them.
8Host 172.16.5.10/16 - network and broadcast?
9How many hosts in /20?
🚀 Section C · Challenge ● CHALLENGE 5
10Why did subnetting matter historically?
