We're not going to agree on this; the answer *was* misleading.  You

which is incomplete.  They are lost from IP, they are not lost in

Nmap may not gather MAC addresses using alternative mechanisms at the
moment, but there is no reason that it can't.  It already interacts with
higher protocols, like RPC and NetBIOS name service, from which it
already gathers the hostname.  The mac address is available via the same

FYI, MS NetBIOS is broadcast which also only works on local subnets,
