Episode 53: IPv6 Subnetting and Address Planning

This episode covers IPv6 subnetting, which operates differently from IPv4 due to its larger 128-bit address space. Instead of conserving addresses, IPv6 subnetting focuses on structured planning and organization. Most IPv6 networks use a /64 subnet, leaving enormous address capacity for each segment. The exam requires you to recognize how IPv6 addressing and subnetting work conceptually, even if calculations are less common than in IPv4.

Practical considerations include allocating subnets for different departments, designing hierarchical addressing schemes, and ensuring efficient routing. The episode also explains how to interpret hexadecimal subnetting and recognize prefix lengths such as /48, /64, and /128. Troubleshooting scenarios are included, such as identifying incorrect prefix assignments or duplicate address issues. Mastering IPv6 subnetting ensures you are comfortable answering exam questions and designing scalable networks in professional practice.
