Network card identification
How to identify who manufactured your Ethernet Network Interface Card
(NIC) and its MAC address:
Getting the MAC address on MS-Windows machines
- First, use netstat -n to determine your network IP address
- Then, use nbtstat -A nnn.nnn.nnn.nnn to determine the
MAC address of your card.
Getting the MAC address on Linux machines
Run the command
This will show the MAC address for the eth0 interface. Run the
command without any parameters to show all interfaces.
Other information, such as the IP address for each interface, is shown.
A similar command will work under most *nix operating systems. Naming
conventions for interfaces vary ('edN' on FreeBSD, for example).
Finding the Manufacturer from the MAC address
- Finally, use the first 6 hex digits in the MAC address to look
up the vendor on the
site. This is reputed to be the definitive list.
- Some older (but more compact) lists may be found
or here (CaveBear) or
here (MIT). There are some further links on these sites which
may be of help.
Unfortunately, not all manufacturers are listed, especially some
newer ones in the Far East.
