Docker defauilts to taking over netowrks 172.17.0.0.  
If this conflicts with other tools such as a VPN which you cannot control, 
you can change the default bridge.   This is easier if you have never started docker.
You wouldnt be reading this if that were the case.
So how to get out of the mess ?

# Bug reports / rfc
https://github.com/docker/docker/issues/8696

# Set the ip of the Docker bridge with Systemd
