I used to think that static IP was the best way to connect my stuff. Big mistake. Once my IP scan got up to 75 devices, managing all those (mostly) static IPs started to get overwhelming. And when I had the same code in two or more nodes on my Home Assistant system (basically sensors), I had to change the IP and recompile each.
DHCP just solves a lot of headaches. I just had about 5 or 6 devices, usually some kind of server, that needed a static IP which the router easily handled.
So, OP, why do you need static IP?
