No this MAC is different Media Access Control, each network adapter has it's own hardware address.
To see if you're getting the same address boot up your PC and check the address in the network connections folder, then connect the HR21 and do a menu->setup->system setup->network->advanced setup I believe will show you what DHCP is assigning to the HR21 as the IP address (I use static so it always shows what I entered).
