MAC Address Vendor Lookup

Each MAC address vendor lookup tool lets users retrieve:

• Vendor Details

  The name of the company that registered the MAC address block, in addition to its street address and country code in ISO 3166 format

• Creation and Update Dates

  The dates when the MAC address block a particular MAC address is part of was registered and last updated

• Registration Details

  Determines if the MAC address belongs to any registered MAC address block

• Validity

  Checks if the syntax of the MAC address of interest is correct

• If It Is Private

  Identifies if the MAC address belongs to a privately registered MAC address block

• Block Details

  Obtains the Left and Right borders, total number of MAC addresses, and assignment type of the MAC address block a specific MAC address belongs to

• Virtual Machine Detection

  Detects if the MAC address is assigned to a virtual machine, in which case the vendor’s name (e.g., VMWare) is given; if the MAC address does not belong to a virtual machine, the result says “Not detected”

• Potential Applications

  If the MAC address and its range is reserved for a specific use case by the vendor, the result will show the higher-level protocol encapsulated in the frame

• Wireshark Notes

  If the OUI or MAC address is in the Wireshark Database, the result provides extra details that help identify its application or actual vendor instead of the original assignment

• Transmission Type

  Determines if the MAC address is a multicast or unicast address

• Administration Type

  Checks if the MAC address is universally or locally administered

• Assignment Block Size

  Checks if the assignment block size is large, medium, small, or individual.
