Comment on I have a rasberry pi 5 collecting dust, what are some neat useful things i can do with it?

DHCP, or the equivalent IP address management GUI, is innocuous… you probably want to use it to specify what static IP you want the Pi to have… but you also need to tell your router DHCP to inform your in-LAN devices that the DNS server they should use is that same static IP when it hands out their assigned IP address.

I don’t really want to do anything with my setup because it works fine. If DHCP is switched on on the pi and not configured to assign addresses to a separate IP range from the router it’s far from innocuous. Some routers also don’t allow DNS settings to be modified so using the pi as DHCP lets you hand out the the pi as the DNS as well.

Pihole comes with DHCP disabled by default for this reason. But you still have to get the router to hand off the Pihole IP as DNS server to all dynamic IP devices.
