Home Assistent and ip static

hi I’m starting to study this great system with excellent results but I’m having trouble configuring it with static ip. I’m using the Hass.io image for raspberry pi3 32bit. I tried to create the usb stick as described in Getting started but nothing. I also tried to add the line ip = [ip number] in cmdline.txt but nothing. I also tried to edit the files in / etc / NetworkManager / system-connections / but it does not exist …

what I would like to do is set a certain range of IP addresses:
192.168.10.1 -> 192.168.10.255
for all the components of my domotic project how do I do it?

I’m not sure I understand what this part has to do with home assistant?

IP addresses are usually set by your DHCP server. In most homes your router is your DHCP server. Configure it there.
