How can i force all client to use dhcp

Hi i have setup radius with dhcp server. How can i force all the people that connect to use DHCP? The reason is so that the radius server can monitor themCan i set something in mikrotik that wil help.

check ‘Add ARP for Leases’ in DHCP server and set ARP mode of your interface to ‘reply-only’. now if user did not receive address via DHCP, he will not be served

Thumbs up for that post. I learned something new today! Thanks.

Thank you for the advice
