mac address lookup
enter a mac address to see the manufacturer of the NIC. Now you can do the opposite, enter a manufacturer to see the mac address' of that organization.
manufacturer data is based on IEEE's listing of OUI/MA-L. The OUI is a 24-bit number that uniquely identifies a vendor, manufacturer, or other organization. the first three octets of the address are the OUI. Expected formats are separated by dashes (ie:hexadecimal notation eg:FF-FF-FF-FF-FF-FF ) or colons (ie:bit-reversed notation eg:FF:FF:FF:FF:FF:FF), as a string of 4 bytes (eg: {FF,FF,FF,FF}), as a base 16 number (eg: FFFFFFFF), or in Cisco IOS format (eg: FFFF.FFFF.FFFF)
( eg : cc46.d6ab.cde0 or 08-84-66-01-23-45 )
