That means you have a second DHCP server on your network, that gets messy very quickly. What possible systems have DHCP servers. Switch them off one at a time (unless they're critical) until you discover which sets the 192.168.100.xxx block.The other weird thing is The RPI always ends up with an IP4 address of 192.168.100.1. But my LAN is 192.168.1.x. The DHCP server (router) is at 192.168.1.2 - there's nothing at 192.168.1.1. I don't know if that has something to do with it or not.
Plug in a TV and keyboard so you can operate your RPi without needing a working network.
