Vendor registration identifies the organization holding a block, not a specific device model, product line, or manufacturing date. This page combines every block IEEE has registered under this exact organization name; it doesn't mean every address in every listed block is currently shipping in a real device.

About Microsoft Corporation

Microsoft's hardware blocks cover Xbox consoles and Surface devices.

Devices that use these prefixes

  • Xbox consoles
  • Surface laptops and tablets
  • Other Microsoft hardware

Randomized MAC addresses

Windows can use random hardware addresses for Wi-Fi, but the setting is off by default, so a Microsoft prefix on a Surface usually reflects the real adapter.
