Devices on network lose IP(v4) address after switching DHCP from router/modem to Pi-Hole

[ChurchOfNoise]

@jfb : just opened /etc/hosts and the line 127.0.1.1 is in there indeed:

The IP of the raspberry pi / pihole on the network is 192.168.1.2, so is that what should be there instead?

I'm a bit surprised the 192.168.1.60 is still mentioned. I'll dig in the dnsmasq files...

just opened /etc/hosts and the line 127.0.1.1 is in there indeed:

This is expected. The problem is that the device at IP 1.60 has the same name.

The problem seems solved, here are the steps I've taken:

• added the Pi-Hole's own IP in the static IP list on the pi-hole
• chose the exact same IP range on the pi-hole as on the router

After doing these two things, both the router AND the Pi-Hole had DHCP enabled in parallel (which I understand is a no-no, yet still...) and some of the traffic used the Pi-Hole, which gave me some confidence.

Then an hour ago or so, I disabled DHCP on the router and so far so good.
