Search for manufacturer by MAC address:

For a manufacturer search using a MAC address, at least the first 6 characters (24 bits or 3 bytes) of your MAC address are required. If also the smallest address ranges assigned by the IEEE are to be searched, the first 20 characters (80 bits) of your MAC address are required. You can enter your MAC address with or without separator ("-" or ":").

You can also search for the name of a manufacturer (at least 3 characters) and get a list of the MAC ranges assigned to the manufacturer. To search for a manufacturer, it is also possible to enter a part of the manufacturer name.

How do I find my MAC address?

The easiest way to get your Mac address under Microsoft Windows is to open the command line or Powershell and enter the command: ipconfig /all. The now displayed Physical Address is the MAC address of your network device. Alternatively, you can enter the name of a manufacturer in the search and receive a list of MAC ranges assigned to the manufacturer.

Under Linux or macOS open a console/terminal window and enter (Linux) "ip link" or (MacOS) "ifconfig /all" there. Here you will find your MAC address under "link/ether“, HWaddr or Hardware Address.

What is the MAC address and where does the data come from?

The MAC address is a 48-bit (12-character) identifier for network devices, which consists of the Organizationally Unique Identifier (OUI) and an individual identifier. The OUI is assigned by the IEEE to manufacturers of network devices and the individual identifier may only be assigned by the manufacturer to a single network device.

In addition to the original OUI database, which uses a 6-character (24 bits) Organizationally Unique Identifier and an identically sized range for the individual identifier, there are now also other databases.

For manufacturers who have a lower demand for MAC addresses, it has been possible since 2014-01-01 to register a smaller/cheaper block with MAC addresses. For this purpose, an MA-M block (for 4096 MAC addresses) or MA-S block (256 MAC addresses) is available. Prior to 01/01/2014, an Individual Address Block (IAB) was available for this purpose, although this database is no longer maintained by the IEEE.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 ranges to disguise the owner while searching for a known wifi network. These MAC ranges are listed under the name Company ID (CID).

For more details on each vendor database, see the IEEE FAQ page.
