hello 

i wanted to use DHCP to assign IP to vmware VM. my VMs are ubuntu. 

i used MAC address that show on Vmware photo: NIC-1.

i create a new ip reservation by mac that show in photo-1 by the client send a UDID and there is no MAC address, photo: NIC-2.

so the client take a new IP address.

what should i do to see client MAC address ?
