You can also search for a manufacturer and see its assigned OUIs.

  • Trusted source - The database is sourced from the IEEE to be as correct and updated as possible.

  • Bulk lookup - You can paste a comma/semicolon/whitespace/new line separated list of MAC Addresses to perform a multiple lookup.
  • Auto-paste from the clipboard when there is one or more MAC addresses
  • Dark theme is supported
