MAC Address API

The MAC address vendor API allows you to retrieve OUI vendor information, detect virtual machines, manufacturer, location, read the information encoded in the MAC address, and get our research's results regarding the given MAC address, OUI, IAB.

For a given MAC address we retrieve

Vendor details

Name of the company which registered the MAC addresses block, it’s street address and country code in ISO 3166 format.

Created & Updated dates

Dates when the MAC address block the given MAC address belongs to was registered and updated the last time.

Block details

For the MAC block the MAC address belongs to, get Left and Right borders, total number of the MAC addresses in it, and assignment type.

Is MAC address registered?

Check if the MAC address belongs to any of the registered MAC blocks.

Is MAC address valid?

Check if the provided MAC address is syntactically correct.

Is MAC address private?

Check if the MAC address belongs to the privately registered block.

Virtual Machine Detection

If the MAC address is assigned to a Virtual Machine, output its Vendor Name (e.g. 'VMWare'), otherwise say 'Not detected'.

Possible applications

Some MAC addresses and their ranges are reserved for specific use cases by their vendors. Such addresses typically indicate what higher-level protocol is encapsulated in a frame.

Wireshark notes

For some specific OUIs or exact MAC addresses, Wireshark Database provides extra details which may help to recognize the MAC address application or indicate an actual vendor rather than the original assignment.

Transmission Type

Determine whether it's a Multicast or Unicast address.

Administration Type

Determine whether it's a Universally or Locally administered address.
