Choosing an IP Scheme

I recently revamped my home network, and as part of the process decided it was time I created an IP scheme and stuck to it.  I’m sure everyone has been guilty of it at some point.  “It’s just a home network, there will only be a few devices, what does it matter… that ones available.”  Fast forward a decade, and multiple leaps and bounds in available technology, and suddenly you have an absolute mess on your hands.  “What IP did I assign to that thing again?”  Next thing you know, there are 40+ devices with IPs (at least in my case).  After thinking it through, this is the scheme I came up with, maybe it will help someone else out.  It leaves plenty of room for future expansion within this particular scope, and I could always add another subnet if necessary, but don’t see myself ever needing that on a home network.
