Episode 53: IPv6 Subnetting and Address Planning
IPv6 changes the game with its enormous address space, but subnetting is still a vital part of organizing and securing your network. In this episode, we explore how IPv6 subnetting works, including how to carve out logical address blocks from a /64 allocation. You'll learn how to plan address spaces using hexadecimal notation, how to keep subnet boundaries readable, and why IPv6 subnetting simplifies many of the challenges seen in IPv4.
We also discuss real-world design considerations such as segmenting departments, isolating services, and ensuring address scalability in hybrid networks. IPv6 planning may feel abstract at first, but with proper structure and prefix documentation, it becomes a powerful tool for managing modern networks. This episode demystifies IPv6 subnetting and makes it accessible even for those new to the format.
