Docker and VMs on new network

I currently have my network using 192.168.1.0/24.

I created a custom docker network called `docker-network` for all of my dockerized containers.

However, I noticed on my router that i keep getting messages like:
 

Multiple devices are using the same IP address: 
192.168.1.100
. Please check each device's configuration to ensure none are communicating with a rogue DHCP server.

and I see that the eth0 MAC address on on my server and the vHost MAC address are both set to 192.168.1.100.

What is the best way to approach resolving this issue? or what's considered best practice?

Should I create another virtual network for just VM's and containers?

Also, here are my current network settings. I'm not sure what is/was default, but does this look okay? Shouldn't bridging be turned on?

Thanks in advance
