How to identify DUID of a client

i try to set a static ipv6 address by dhcpv6 server, but i don’t know the DUID of the client, does it exist a command or a dhcpv6 server option to show in logs or in the console the list of DUIDs of clients that they have received a dhcpv6 address by the server?
Thank you
