Hello,
I seem to be getting odd MAC addresses showing when I run "sh ip dhcp bind" on any of 3 Cisco routers with DHCP enabled that I have.
(see pic)
Am I missing something here? Is 013c.15c2.2b1f.23 a valid MAC address?

Hello back
The 01 component of this is a media type (01 means that it is Ethernet - I haven't seen any other values). Some operating systems (e.g. Windows) send this along with the MAC address 3c15.c22b.1f23 as the client identifier.
You can also set the option in a Cisco device that uses DHCP for obtaining and address. An example can be found here - search for media type
