All,
I have this doubt:
If the user provides a locally administered MAC address (either thru'
the Adapter's Properties Menu, or
thru' the Windows registry ), all applications show the changed
address as the MAC address.
Refer : http://www.terena.nl/tnnc/1B/1B2/1B2.html (last but one
para)
I understand this is the expected behavior.
But how do i get the hard-coded (burnt) MAC address of the NIC when
the local MAC address is provided?
ipconfig /all
net config workstaion
both return the modified MAC address.
I ran small applications that fetch the MAC address of the NIC.
Ref : http://www.pcausa.com/resources/ndisfaq.htm#FindMACAddress
But all these applications (NDIS, NetBIOS, SNMP, etc) return the
modified MAC address and not the burnt,
hard-coded MAC address.
Is there no way to obtain the MAC address from the NIC directly?
If there is not, then what is the security that is provided by these
cards? (because i can change the
MAC address to whatever i want to, then it wouldn't be unique ->
result : chaos!!!!)
SO does any one know how to obtain the burnt,
hard-coded MAC address from the NIC directly , even when the local MAC
address is provided.
In anticipation.......
