IP Addressing & Subnetting
Understand how IP addresses work and learn to divide networks efficiently using subnet masks, CIDR notation, and Variable Length Subnet Masking (VLSM). This module is essential for real-world network design and CCNA preparation.
What You’ll Learn
- Understand IPv4 structure: Network, Host, and Broadcast addresses.
- Calculate subnets using CIDR and subnet masks.
- Learn how VLSM optimizes IP address usage.
- Design scalable and efficient network topologies.
