// This is a very simple configuration of an IPv4 DHCP server.
// The most important settings are here, and the subnet defined _should_ be
// compatible with the default Docker bridge network unless you have modified
// your Docker config. This is done so it should be easy to test the DHCP
// functionality without worrying that "real" lease offers leaves your machine.
