debops.dhcpd role can be used to configure an ISC DHCP Server as
standalone or in a 2-host failover configuration. Alternatively, you can
configure an DHCP relay on a host connected to multiple networks which will
relay DHCP/BOOTP messages to your DHCP server.
dhcp-probe script will be used to scan the network for unauthorized DHCP
servers and notify administrators if they are found.
