Search for manufacturer by MAC address:

Help / Tutorial

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 (- 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 ifconfig there. Here you will find your MAC address under HWaddr or Hardware Address.

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

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.

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 Before 01.01.2014, an Individual Address Block (IAB) was available for this purpose, whereby this database is no longer maintained by the IEEE.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. These are listed under the name Company ID (CID).

Further details on the individual vendor databases can be found on the IEEE FAQ page.
