I have been setting up PiHole and got it all working with the router. I am keeping the router as the DHCP, as everything is working fine. But suddenly I noticed 4 devices have been assigned a Static IP. I never assigned these, and they are not on the list of manually assigned IPs either. You can see in the screenshot below, I have some manual devices, which I setup, but now their are 3 devices that say static IP, but have not been touched at all, they were on DHCP not long ago. I don't understand how, where or why these devices have been assigned a static ip.
