For some strange reason, my Raspberry Pi is acting as the DHCP server on my home network. Whenever a computer boots up in our house, it's immediately told that the IP address for the DHCP server is my Pi.
I don't know if there's some way to prevent such an assignment outside of static setup (which is what our "main" computer is on now as a workaround), or whether it's something that needs to be done in the router admin page or in the Pi. I would like to prevent just turning off the Pi because I'm trying to keep it open as a file offload server.
My router - Netgear R6200, firmware V18.104.22.168_1.0.41 - is on 192.168.1.1, and my Pi is on 80 - every other device we own filters in between those two addresses.
