IPv4 Subnetting

This lecture introduces decimal and binary numbering systems, explains how to read an eight-bit chart, defines bits, bytes, and octets, and demonstrates decimal-binary conversions for subnetting.

Learn binary math with ones and zeros, perform addition and subtraction, convert between binary and decimal, and apply these techniques to subnetting using octets.

Master hexadecimal basics, where digits 0–9 and a–f represent values, grouped in four bits to map to binary. Learn to convert hex, binary, and decimal with concrete examples.

Explore why we subnet to reduce broadcast domains and improve network segmentation. Master slash notation, octet boundaries, and fixed or variable length subnetting formulas for subnets and hosts.

Explore fixed length subnetting across class A, B, and C boundaries (slash 8, 16, 24) and identify network id, host portions, and private addresses.

Explore variable length subnet masks (VLSM) to design flexible subnets, calculate usable and host addresses, and apply binary grouping and octet rules to meet diverse host needs.

Engage in an IPv4 subnetting project by subnetting five networks with specified usable hosts and ranges, and complete five-question assignments to practice subnetting.
