The data displayed here are provided by the IEEE and have been prepared by us for the search function. These MAC ranges are listed under the name Company ID (CID).įurther details on the individual vendor databases can be found on the IEEE FAQ page. Some smartphones use these MAC areas to disguise the owner while searching for a known Wifi network. 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. Before, an Individual Address Block (IAB) was available for this purpose, whereby this database is no longer maintained by the IEEE. For this a MA-M block (for 4096 MAC addresses) or MA-S block (256 MAC addresses) is available.

Since it is possible for manufacturers who have a lower need for MAC addresses to register a smaller/cheaper block with MAC addresses. This identifier forms the first 3 bytes (6 characters) of the MAC address for the manufacturer's network devices. This identifier is assigned by the IEEE to manufacturers of network devices. 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. What is the MAC address and where does the data come from? Here you will find your MAC address under 'link/ether“, HWaddr or Hardware Address. Under Linux or macOS open a console/terminal window and enter (Linux) ' ip link' or (MacOS) ' ifconfig /all' there. Alternatively, you can enter the name of a manufacturer in the search and receive a list of MAC ranges assigned to the manufacturer. The now displayed Physical Address is the MAC address of your network device.

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. To search for a manufacturer, it is also possible to enter a part of the manufacturer name. 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. You can enter your MAC address with or without separators ( - or :). 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. For a manufacturer search using a MAC address, at least the first 3 bytes (6 characters) of your MAC address are required.
