MAC adress and Network Adapter product details

MAC addresses are most often assigned by the manufacturer (universally administered addresses) of a network interface controller (NIC) and are stored in its hardware. The The first three octets in universally administered addresses identify the organization that issued the identifier and are known as the Organizationally Unique Identifier (OUI). However OUI is generally missing in a locally administered address I as it is generally assigned to a device by a network administrator, overriding the burned-in address.

You can use following service (http://standards.ieee.org/develop/regauth/oui/public.html) to get the details about the manufacturer of a NIC, all you have to do is to enter the first three groups of your MAC address e.g. if your MAC address is 01-23-45-67-89-ab, then enter 01-23-45.
