source of supply for MAC addresses

source of supply for MAC addresses

[Jörg Huwig]

Hi all,

for an own manufactured device based on a Motorola MPC850,
we need unique MAC addresses for the ethernet port.
Could anyone give me the information were we can get such unique addresses?

Thanks in advance,


Joerg

You can buy them from IEEE.

See http://standards.ieee.org/regauth/oui/index.shtml

First you should request an OUI (see
http://standards.ieee.org/regauth/oui/index.shtml). It is used as the
left part (3 bytes) of an ethernet MAC address.
Then you have to assign the other 3 bytes and ensure that one MAC
address never is used twice.
To accomplish this you can use the serial number of your device or
special chips that contain such unique numbers.

Hi,

To have your own MAC addresses, you must fill a form
on the following site
http://standards.ieee.org/regauth/oui/forms/

Then you receive all detailed operations.
