The startup/running config should show them.

HI Gamar,

If the router is configured as DHCP server then you can use 'show ip dhcp pool" to see excluded ip address and "Sh run | be router dhcp" will provide the exact configuration

Command:  sh ip dhcp bind

As said by Leo, the DHCP bindings will show the corresponding MAC addresses.

Unless you have a list of all MAC addresses somewhere (which most people tend not to) then you can use the ARP cache combined with the CAM tables to trace which ports relate to which MAC address to get more information on the host if you need it.
