MAC address vendor

ACUTE COMMUNICATIONS CORP. — MAC Prefix Identification

Primary prefix
00:D0:F9
Block
MA-L

Summary

// what this is
Acute Communications is registered to MAC prefix 00:D0:F9 in the IEEE OUI database. When a device's MAC address begins with 00:D0:F9, that block was registered by Acute Communications — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
The 24-bit prefix fixes the first octet at 00, so its Group and Local bits are both zero. It matches the first three octets; the 24-bit suffix permits 16,777,216 possible values, not a device or shipment count. A prefix match identifies a registry assignment, not a particular device or current operator.

About this vendor.

Updated  ·  Confidence: High  ·  2 sources  ·  How this page is checked

A MAC address beginning 00:D0:F9 is registered to ACUTE COMMUNICATIONS CORP.; the available evidence does not identify a device type or product for this prefix. The IEEE MA-L record lists the company name and indicates Taiwan, but a registry assignment does not establish where the prefix is deployed or who currently operates a device using it.

The assignment is a 24-bit prefix, so it matches the first three octets of a 48-bit MAC address. The remaining 24 bits allow 16,777,216 possible suffix values; this is a mathematical address space, not a count of devices or shipments. In the first octet 00, the Group and Local bits are both zero. Those bits are fixed for an exact 00:D0:F9 match; changing either bit produces a different prefix.

RFC 7042 describes the significance of these bits and the structure of MAC identifiers.
