MAC Address Block Large (MA-L) This product was previously referred to as an OUI (Organizationally Unique Identifier) and is still referred to as such in many standards. OUI is an IEEE Registration Authority (RA) specific term that is referred to in various standards and may be used to identify companies on the IEEE Public Listing. // Accepted MAC Address Formats. Send your MAC address in any shape or form and our server should be able to handle it. Separated by periods? Separated every 2 characters? 4 characters? Not a problem. Generally, MAC addresses will come in the following shape or form: 00-11-22-33-44-55; 00:11:22:33:44:55; 00.11.22.33.44.55.
Mac Address To Vendor Lookup
Search by Ethernet MAC address, OUI, or Bluetooth device address: Enter complete MAC address or at least first six characters including all leading zeros. For example: 00-16-68 or 00-16-68-2B-40-90 or 00:16:68:2B:40:90 or 0016682B4090 or 00.16.68.2B.40.90. For bulk MAC address lookup use this tool.
Search by Fibre Channel WWN address: Enter complete WWN address including all leading zeros. For example: 210000e08b02e345 or 10:00:00:60:69:00:23:74 or 10.00.00.60.69.00.23.74. Search by NAA 6 128-bit WWN is also supported. NAA 6 WWNs are used as LUN or disk identifiers. For example: naa.600a098038303466302776626358764d, /dev/dsk/c6t60020F200000CA933D7719CA00088BB5d0s0 (WWN is highlighted). For bulk WWN lookup use this tool.
Search by vendor: Enter at least three alpha-numeric characters to match any part of vendor’s name. For example: IBM or Cisco. One- and two-character search strings are also accepted and will match only a whole part of vendor’s name. For example: a search for AT will bring At Work Computers, AT&T and so on; a search for L will bring L.S.I. Japan Co., Ltd. and L-3 Communication Aviation Recorders, etc.

For a manufacturer search using a MAC address, at least the first 3 bytes (6 characters) of your MAC address are required. If even the smallest address ranges assigned by the IEEE are to be searched, the first 5 bytes (20 characters) of your MAC address are required. You can enter your MAC address with or without separators (

The MAC address is a 24 bit (12 characters) long identifier of network devices, which is also called Organizationally Unique Identifier (OUI) or MA-L. This identifier is assigned by the IEEE to manufacturers of network devices. This identifier forms the first 3 bytes (6 characters) of the MAC address for the manufacturer's network devices.
Mac Address Vendor Database Downloads
Since 01.01.2014 it is possible for manufacturers who have a lower need for MAC addresses to register a smaller/cheaper block with MAC addresses. For this a MA-M block (for 4096 MAC addresses) or MA-S block (256 MAC addresses) is available. Before 01.01.2014, an Individual Address Block (IAB) was available for this purpose, whereby this database is no longer maintained by the IEEE.

In addition to the MAC addresses for network devices, it is also possible to reserve a MAC block for applications that do not require a globally unique MAC identifier. Some smartphones use these MAC areas to disguise the owner while searching for a known Wifi network. These MAC ranges are listed under the name Company ID (CID).
Further details on the individual vendor databases can be found on the IEEE FAQ page.
