How to discover the mac address of machines in a network?
For machines which have an OS installed, you can use an nmap
ping sweep, or ARP request to get your local OS to learn other
MAC IDs.
I need to discover the machines that are available just with only BIOS
installed (NO Operating System)
And I need to find the mac address of such machines that are up.
Unless a machine starts transmitting any data on the network,
you can't find any information about it.
If your BIOS attempts PXE boot, you can capture the MAC ID
from the DHCP broadcast request. Or if you have a managed
L2 switch, you can query its ARP table for list of all MAC IDs
it has learned.
to do something more useful.
