We all go down this hole at the start. The truth is, you should only reserve IPs if you actually need it to stay the same. You don’t need to check IPs as often as you think, I promise. The only segmentation and planning you should do for a home network is for subnets/vlans; LAN, Guest, IOT, Server, etc.
Instead of managing the IP addresses, just manage hostnames. Make sure every device with a customizable hostname is easily identifiable. This will help you so much more in the long run.
