Show Dhcp assigned IPS with respective MACs.

I have Freeradius 3.0.21 on Ubuntu 18.04 LTS Server (no X) acting as Radius itself and as Dhcp one. There is no Freeradius Web UI installed at the time. What are ways to show assigned IPs by DHCP respectively with its MACs from CLI and from some Web UI something like: MAC IP Assignment time Lease (or RElease) time
